BACKGROUND

Riflescopes have been used for well over a century and while the qualityand features of these devices have improved tremendously over the years,the core components (and the limitations of those components) used intheir design, manufacture and use are still very much the same today asthey were 100 years ago. Riflescopes create a magnified or unmagnifiedimage of a scene that is distant from the shooter on a focal plane,which is coincident with an aiming feature, or reticle. The reticleconsists of wire or a material deposited in a pattern onto a glasssurface and it is used as an aiming reference, which corresponds to thetrajectory of the rifle to which it's attached. The reticle may alsohave specific features included to aid the shooter in making distancejudgements and in compensating for bullet deviation at differentdistances.

Turrets are also used to make adjustments to the reticle position inrelation to the target in order to compensate for bullet deviation. Thisis a very developed and reliable system that can be used in the hands ofthe experienced and skilled shooter to make challenging long rangeshots. With the aid of a laser rangefinder (LRF) and a ballisticcomputer and careful attention to detail, an experienced shooter canroutinely hit targets at the maximum effective range of their firearm bymaking the necessary mechanical adjustments to the firearm and/orexecuting the correct holds on the reticle pattern.

While this system performs well, there is always a desire to improveupon the system. In particular, there is a desire to reduce thecomplexity involved in hitting long range targets. A large amount ofinformation is needed on a shot-by-shot basis in order to effectivelyhit long range targets and the shooter must be able to process thisinformation and make the correct judgments and calculations in realtime. In addition to the riflescope, other tools are needed by theshooter to ensure accurate shot placement. For instance, a bubble levelmounted externally to the riflescope is needed to ensure that the opticis level before executing a shot. This requires the shooter to removehis head from the pupil of the optic to check his or her level.

A laser rangefinder and ballistic computer are also needed to measuretarget range and calculate a bullet trajectory. This once again requiresthe shooter to attend to an external device and then remember the datawhen making the necessary adjustments. If a weapon mounted laserrangefinder is used, then the shooter needs to take special care toensure that the aiming point of the optic is corresponding exactly withthe aiming point of the LRF.

Additionally, and not trivial to the use of riflescopes, is that theyare only useful during daylight hours. Once night begins to descend,thermal and/or night vision devices must be attached to the weapon infront of the riflescope. These devices capture other forms of radiationthat are not visible to the human eye due to their wavelength or lowintensity. These devices then either recreate the image of the scene orintensify it and reimage the scene into the objective of the riflescope.Effective and necessary for low light conditions, these devices are alsoheavy and large.

In the particular case of thermal imaging devices, a thermal scene isimaged via infrared optics onto a special thermal sensor. The image isthen recreated on a micro display and the micro display is, in turn,reimaged into the objective of the riflescope with a visible opticssystem. The two separate optical systems required to accomplish thisresult in a rather large, heavy, and expensive device.

As technology advances, there is a need for some level of systemintegration in order to reduce the heavy processing requirements placedon the shooter. This integration is also required to decrease the “timeto engagement” that is traditionally quite long when multiple deviceshave to be referenced and calculations and adjustments have to be made.And finally, the size and weight of additional devices needed foreffective use of the riflescope in low light conditions can be reducedwith a more integrated solution.

Previous devices have attempted to address some of these issues indifferent ways with varying degrees of success. However, all attemptsprior have implemented their solutions in the Second Focal Plane of theoptic. This is very disadvantageous because the second focal plane in ariflescope is only well correlated to the image of the scene at a singlemagnification setting. The location of the aiming point is only accurateat one location in the turret adjustment as well. Because of thisserious limitation, additional electronics are necessary to track thevariables in the rest of the system and adjust the aiming pointaccordingly. Other systems provide approximate aiming point solutionsthrough the illumination of features at generic, coarsely-spacedintervals instead of having a quasi-infinite range of points to select.Weaker systems are only capable of displaying basic information such asdistance to target or current weather conditions.

Thus, a need still exists for a viewing optic that can projectinformation into the first focal plane of an optical system. Theapparatuses, systems, and methods disclosed herein address all of theseshortcomings in an innovative fashion.

II. Viewing Optic

FIG. 1A illustrates the traditional design of a riflescope, which is arepresentative example of a viewing optic. FIG. 1B illustrates anexemplary viewing optic 10 in accordance with embodiments of thedisclosure. Specifically, FIG. 1B illustrates a riflescope. Moreparticularly, the riflescope 10 has a body 38 that encloses a movableoptical element 15. The body 38 is an elongate tube tapering from alarger opening at its front 40 to a smaller opening at its rear 42. Aneyepiece 56 is attached to the rear of the scope body, and an objectivelens 54 is attached to the front of the scope body. The center axis ofthe movable optical element defines the optical axis 44 of the riflescope.

An elevation turret 12 and a windage turret 48 are two dials that areoften found in the outside center part of the body 38. They are markedin increments by indicia 20 on their perimeters 11 and are used toadjust the elevation and windage of the movable optical element forpoints of impact change. These dials protrude from the turret housing50. The turrets are arranged so that the elevation turret rotation axis46 is perpendicular to the windage turret rotation axis 52.

FIG. 1C shows a cross-section view of the sighting device from FIG. 1Bwith the basic components of optical system 14 and moveable opticalelement 15. As shown in FIG. 1C, optical system 14 includes an objectivelens system 16, erector system 25, and eyepiece lens system 18. FIG. 1Cshows a riflescope having a body 38, but optical system 14 could be usedin other types of sighting devices as well. Erector system 25 may beincluded within a moveable optic element 15. The erector system 25 mayinclude a power varying lens element or zoom element 25A. In FIG. 1C,moveable optic element 15 also includes a collector 22, as well as firstfocal plane reticle 55 and second focal plane reticle 57. When in use,adjustment of turret assembly 28 and turret screw 29 causes adjustmentof moveable optic element 15.

The movable optical element 15 is adjusted by rotating the turretassembly 28 one or more clicks. As the turret is rotated, a turret screw29 moves in and out of the scope, which pushes the erector tube. Theerector tube is biased by a spring so when the turret screw is adjusted,it locates the erector tube against the bottom face of the turret screw.The erector tube provides a smaller view of the total image. As theerector tube is adjusted, the position of the reticle is modifiedagainst the image.

A reticle is a circular, planar or flat transparent panel or diskmounted within the scope body in perpendicular relationship to theoptical axis or line-of-sight through the scope, and is positionedbetween the objective lens element 54 and the erector lens element,typically at a site considered to be a front focal plane of the opticalsystem within the housing. In one embodiment, the reticle contains fineetched lines or hairline indicia comprising a center vertical hairlineand a center horizontal hairline, which orthogonally or perpendicularlyintersect at a center point.

In one embodiment, as shown in FIG. 1D, the viewing optic can have aparallax adjustment knob 70 or a focus knob. Parallax occurs when theoptical plane of the image of a target is not coplanar with the opticalplane of the image of the reticle. As a result of the offset between thetwo optical planes, the reticle can appear to move relative to thetarget when the marksman moves their eye around the center of thereticle. This parallax error can result in a shift in the point ofimpact from firing. The parallax adjustment of a viewing optic enablesthe marksman to eliminate optical error at different distances, byenabling the optical system to be adjusted to show the image of thetarget and the image of the reticle in the same optical plane. Parallaxcompensation changes neither the focus of the reticle nor the focus ofthe image; it simply moves the planes at which these two objects are infocus so that they share the same plane (are coincident).

As shown in FIG. 1D, the viewing optic can have a side wheel mounted tothe rotatable parallax adjustment knob 70. The larger diameter of theside wheel provides more space for markers, such as range marker, to beapplied, and is easier for the marksman to rotate and read when in use.The larger diameter of the side wheel serves to increase the accuracyand resolution of the range finding markers.

FIG. 1E shows a close-up view of an optical system 14 in cross-section,illustrating how light rays travel through the optical system 14.Optical system 14 may have additional optical components such ascollector 22, and it is well known within the art that certaincomponents, such as objective lens system 16, erector system 25, andeyepiece lens system 18 may themselves have multiple components orlenses.

In one embodiment, the viewing optic can have a focusing cell having oneor more adjustable lens for providing parallax adjustment. In oneembodiment, the one or more adjustable lens is one or parallax lenses.

In one embodiment, a focus lens is located between an ocular lens and anobjective lens. The relative distance between the focus lens and theobjective lens is adjustable, for providing parallax adjustment. Inaddition, erector lenses are located between the ocular lens and thefocus lens. The relative distance between the erector lenses and theobjective lens is adjustable, for providing magnification adjustment.

III. Viewing Optic with an Active Display

In one embodiment, the disclosure relates to a viewing optic having anactive display that generates a digital image and projects the digitalimage into the first focal plane of the viewing optic. In oneembodiment, the disclosure relates to a viewing optic that has an analogreticle and a digital image, including but not limited to a digitalreticle, visible to the user when looking through the viewing optic. Inone embodiment, the viewing optic can be used with an external laserrangefinder with ballistic calculation capability.

In one embodiment, the viewing optic has a moveable erector tube with ananalog reticle or a glass etched reticle that is mounted to the erectortube in such a way that the analog or glass etched reticle moves inconjunction with said erector tube. In one embodiment, the digitallyinjected reticle does not move in conjunction with the erector tube.Thus, the digital reticle is accurate regardless of the turret orerector tube position.

In one embodiment, the disclosure relates to viewing optic with adigital display that can be injected into the first focal plane of theviewing optic such that the image of the digital display on the firstfocal plane is not tied to the movement of the erector tube. In oneembodiment, the display can give users accurate ballistic hold points ofaim, regardless of the erector tube/turret position of the riflescope.

In one embodiment, the disclosure relates to viewing optic with anaiming point that is agnostic to the position of the erector tube and/orturret position of the viewing optic. In one embodiment, if aballistically determined aim point is beyond the field of view of theerector unit, the turrets can be dialed to bring the ballisticallydetermined aimpoint into the field of view.

In one embodiment, the viewing optic has a main optical system comprisedof an objective lens system that focuses an image from a target down toa first focal plane (hereafter referred to as the “FFP Target Image”),followed by an erector lens system that inverts the FFP Target Image andfocuses it to a second focal plane (hereafter referred to as the “SFPTarget Image”), a beam combiner that is placed between the objectivelens system and the FFP Target Image, an eyepiece lens system thatcollimates the SFP Target Image so that it can be observed by the humaneye, and a second optical system.

In one embodiment, the second optical system has an active display, anda lens system that collects the light from the active display. The imagefrom the digital display is directed to the beam combiner so that thedigital image and the target image from the objective lens system can becombined at the first focal plane and viewed simultaneously. In oneembodiment, the second optical system can have a reflective material,including but not limited to a mirror.

Referring to the description above, the digital display is injected intothe main optical system, between the objective lens system and the firstfocal plane, and then is focused onto the first focal plane. At thefirst focal plane, both the digital image from the digital display andthe analog/glass etched reticle attached to the erector lens systemshare the same plane. However, the analog reticle is attached to amoveable erector lens system, while the image from the digital displayis not. Therefore, if the erector lens system is moved, the analogreticle will move, but the digital image will remain stationary.

In one embodiment, the viewing optic can be rigidly mounted to afirearm. In another embodiment, a laser rangefinder can be mounted toeither the firearm or the viewing optic. The laser rangefinder measuresthe distance to the target, computes the ballistics for hitting thattarget, provides that information into the active display so that thecorrect point of aim can be displayed with the point of impact of therifle bullet.

It is important that the digital image remain stationary because thelaser range finder is rigidly attached to viewing optic and its point ofaim does not move. This allows the digital display to be digitallyadjusted so that the digital laser designator corresponds with the laseron initial setup, and then the two will always remain in alignment, nomatter how the erector lens system is moved.

Additionally, the barrel of a firearm is rigidly attached to the viewingoptic, so the point of aim of the barrel never changes in relation tothe digital display. This allows the digital display to be digitallyadjusted so that a digital aim point corresponds with the barrel of thefirearm at its initial “sight-in” distance during initial setup, andthen the two will always remain in alignment.

When the need arises to shoot at different distances than the initialsight-in distance, the laser range finder can measure the distance andthen do ballistic calculations to determine the new location of thepoint of aim. That new point of aim location is always relative to theinitial sight in distance, so the riflescope simply needs to adjust thedigital display aim point to correspond with the new point of aim.

A side benefit of this system is that, because the digital aim point isstationary, the user can easily test the accuracy of the turrets on theviewing optic that adjust the erector tube position using a reticle thathas predetermined marks on it at regular intervals. As the erector tubemoves, the reticle can be measured against the stationary digital aimpoint to see if the adjustment dialed on the turrets match the amount ofmovement measured between the digital aim point and the reticle attachedto the erector lens system.

In one embodiment, the base is attached toa bottom portion of the main body. In one embodiment, a gasket is usedto enclose the main body and the base.

In one embodiment, the disclosure relates to a riflescope having a mainbody with an optics system for generating images of an outward scene anda base coupled to the main body with an integrated display system forgenerating digital images and directing the digital images into a firstfocal plane of the optics system, thereby providing simultaneous viewingof the digital images and images of the outward scene.

In another embodiment, the disclosure relates to a riflescope having amain body with an optics system for generating images of an outwardscene and a base coupled to the main body with an integrated displaysystem having an active display for generating images and directing thegenerated images into a first focal plane of the optics system providingsimultaneous viewing of the generated images and images of the outwardscene when looking through an eyepiece of the scope body.

In a representative embodiment, FIG. 2 displays a side view of ariflescope 200 with a main body 210 and a base 220. In one embodiment,the base 220 is separable from the main body 210. The base 220 attachesat one end of the scope body near the magnification ring 212 and at theother end of the scope body near the objective assembly 214. In oneembodiment, the main body 210 and the base 220 are made of the samematerial. In another embodiment, the scope body and the base are made ofdifferent material.

A. Main Body

In one embodiment, the main body is the shape of an elongate tube, whichtapers from a larger opening at its front to a smaller opening at itsrear and an eyepiece attached to the rear of the elongate tube, and anobjective lens attached to the front of the elongate tube. In oneembodiment, the first housing is a main body of a riflescope.

In one embodiment, the main body has a viewing input end, and a viewingoutput end, which can be aligned along viewing optical axis 44 (FIG.1B), and can be inline. Objects or targets can be directly viewed by theeye of the user through the viewing input end, along the viewing directview optics, and out the viewing output end. The main body can includean objective lens or lens assembly at the viewing input end. A firstfocal plane reticle can be positioned and spaced along the viewingoptical axis A from the objective lens assembly.

In one embodiment, a picture or image reversal lens assembly can bepositioned and spaced rearwardly along the viewing optical axis A fromthe first focal plane reticle. An erector tube having an erecting imagesystem is located within the main body between the objective lens andthe ocular lens in order to flip the image. This gives the image thecorrect orientation for land viewing. The erecting image system isusually contained within an erector tube.

The reversal lens assembly or erecting image system can comprise one ormore lenses spaced apart from each other. The erector image system mayinclude one or more movable optical elements, such as a focus lens thatis movable along its optical axis to adjust the focus of the image and amagnification lens movable along its optical axis to optically magnifythe image at the rear focal plane so that the target appears closer thanits actual distance. Typically, the erector assembly includes amechanical, electro-mechanical, or electro-optical system to drivecooperative movement of both the focus lens and one or morepower-varying lens elements of the magnification lens to provide acontinuously variable magnification range throughout which the erectorassembly produces a focused, erect image of the distant target at therear focal plane.

Variable magnification can be achieved by providing a mechanism foradjusting the position of the erector lenses in relationship to eachother within the erector tube. This is typically done through the use ofa cam tube that fits closely around the erector tube. Each erector lens(or lens group) is mounted in an erector lens mount that slides withinthe erector tube. An erector sleeve attached to the erector lens mountslides in a straight slot in the body of the erector tube to maintainthe orientation of the erector lens. The erector sleeve also engages anangled, or curving, slot in the cam tube. Turning the cam tube causesthe erector lens mount to move lengthwise within the guide tube, varyingthe magnification. Each erector lens will have its own slot in the camtube and the configuration of these slots determines the amount and rateof magnification change as the cam tube is turned.

An aperture in a second focal plane can be positioned and spacedrearwardly along the viewing optical axis A from the picture reversalassembly. An ocular lens assembly can be positioned and spacedrearwardly along the viewing optical axis A from the aperture in thesecond focal plane, at the eyepiece. The ocular lens assembly caninclude one or more lenses spaced apart from each other. In someembodiments, the viewing optical axis A and the direct viewing opticscan be folded.

In one embodiment, the main body has a beam combiner. In one embodiment,the beam combiner can be positioned on and optically coupled to aviewing optical axis 44 as shown in FIG. 1B. In one embodiment, a beamcombiner can be positioned near a viewing optic reticle. In anotherembodiment, a beam combiner can be positioned near a first focal planeviewing optic reticle.

In one embodiment, the beam combiner is located between the objectiveassembly and the first focal plane.

In still another embodiment, the main body has a beam combiner, whereinthe beam combiner is not located near the ocular assembly. In oneembodiment, the beam combiner is not located beneath the ocularassembly.

In one embodiment, the main body has a beam combiner that is locatedcloser to the objective assembly as compared to the ocular assembly inthe main tube of the viewing optic.

As shown, riflescope 300 has an objectiveassembly 310, a beam combiner 320, a first focal plane 330, a secondfocal plane 350, and an ocular assembly 360. The beam combiner 320 islocated between the objective assembly 310 and the first focal plane330.

In one embodiment, the viewing optic 400 can have a main body 210 thatis longitudinally split to allow for assembly of the associated lensesand circuitry in the base 220. FIG. 4 is a representative example of alongitudinally split main tube 210 of a riflescope 400. FIG. 4 depictsthe parting line 410 of the longitudinally split main tube. The split420 in the bottom side of the main body 210 allows for coupling of abase 220 having an integrated display system.

In one embodiment, the bottom side of the main body has a longitudinalsplit. In one embodiment, the longitudinal split is approximately thelength of the base that couples to the main body.

In one embodiment, the main body does not have an active display.

3. Magnification Tracking System

In one embodiment, the disclosure relates to viewing optic and methodsfor tracking the magnification setting of a viewing optic, wherein thecomponents of the tracking mechanism are reliable, completelytransparent to the operator, and environmentally protected.

When a reticle is in the first focal plane, the reticle is in front ofthe erector system and thus the reticle changes proportionally with thechange in lens position creating a magnified image. The erector systemchanges position through the use of a magnification ring that is locatedon the external portion of a rifle scope near the ocular housing.Typically, a magnification ring is connected with a screw to an outererector sleeve, forcing the outer erector sleeve to rotate with themagnification ring when rotated causing cam grooves to change theposition of the zoom lenses located in the erector system. Whenprojecting a digital image onto the first focal plane it is necessary toscale that image with the scaling of the reticle to make the digitalimage usable.

The magnification adjustment mechanism is coupled to the power-varyinglens or zoom lens element, which provides the ability to adjust anoptical magnification of the image of the distant object.

In one embodiment, and as shown in FIG. 6 , a potentiometer wiper 610 islocated on the outside diameter of an outer erecter sleeve 620. Thepotentiometer wiper contacts a membrane potentiometer 710 located on theinternal diameter of the main body 210 of the riflescope (see FIG. 7 ).

As shown in FIG. 8 , in one embodiment, the potentiometer wiper 610 is aflat spring with two points of contact to insure it maintains contactwith the membrane potentiometer 710. The flat spring is located betweenthe outer erector sleeve 620 and inner erector tube. The potentiometerwiper 610 is located on the inside diameter of the riflescope on theopposing inner wall of the magnification ring slot screw 820. Thepotentiometer wiper 610 is fastened to the side inner side of the scopetube using adhesive.

In one embodiment, the potentiometer wiper has the ability to laycompletely flat on the outside diameter of the outer erector sleeve. Inone embodiment, the potentiometer wiper is placed internally on theouter erector sleeve.

In one embodiment, the potentiometer wiper is not placed on themagnification ring 810 of FIG. 8 .

The magnification tracking system disclosed herein is located internallyand no part is exposed to the environment, which offers a fewadvantages. First, the system is internal resulting in no seals beingneeded to protect the wiper/erector system from the environment.Secondly, magnification tracking system is completed when the erectorsystem is installed into the riflescope. This eliminates the possibilityfor debris to enter the system through a screw hole on the exterior ofthe magnification ring.

In one embodiment, the disclosure relates to a system for trackingmagnification setting of a viewing optic, wherein the system uses asensor and a material that has varying degrees of opticalreflectance/absorption.

In one embodiment, the PCB has an LED and a photosensor. In oneembodiment, the LED and photosensor are located directly beneath thegradient strip, which is attached to the outer diameter of the outer camsleeve. The LED illuminates the gradient strip and the photosensorreceives a portion of the light reflected off the gradient strip, whichcan then send a signal to a microcontroller, wherein the strength of thesignal varies with the amount of light detected.

When the magnification adjustment ring is rotated by the operator adifferent portion of the gradient strip is exposed to the LED andphotosensor, which in turn changes the signal strength sent to amicrocontroller. The optical magnification setting of the system istherefore able to be tracked by associating it with the amount of lightdetected by the photosensor.

As depicted in FIG. 15 , the images generated from the micro display1210 can be redirected from the display optical axis A onto the viewingoptical axis A through a mirror 1230 to a beam combiner 320 in the mainbody 210 for simultaneously superimposing or overlaying into the firstfocal plane 1510 the digital images onto the images of the scene viewedby the viewer through the optics. Because the beam combiner 320 ispositioned before the first focal plane 1510, and the combined image isfocused on the first focal plane, the displayed image and the viewedimage do not move in relation to one another. This is a majoradvancement compared to devices that inject the image into the secondfocal plane.

In one embodiment, as shown in FIG. 16 , the active display 1210 islocated in a portion of the base closest to the objective assembly 214as compared to the ocular assembly of the main body of a riflescope,when the base is coupled to the main body of a riflescope. The main bodyof the riflescope has an analog reticle 1610.

FIG. 17 depicts the riflescope 200 with a main body 210 with a beamcombiner 320 and a base 220 coupled to the main body and having anintegrated display system. As shown in FIG. 17 , the active display 1210is located in a portion of the base closest to the ocular assembly ascompared to the objective assembly of the main body of a riflescope,when the base is coupled to the main body of a riflescope. Bysuperimposing the image from the integrated display system onto thefirst focal plane, the user is still able to use a traditional glassetched reticle 1610 for aiming purposes.

In one embodiment, the integrated display system can direct generatedimages from the active display along a display optical axis A. Thegenerated images can be directed from the display optical axis A to amirror in the base to a beam combiner in a main body of a riflescope forsimultaneously superimposing or overlaying the generated images onto theimages of the scene viewed by the viewer through an optics system of themain body, wherein the combined image is injected into or focused ontothe first focal plane of the optic system of the main body.

In one embodiment, the image generated from the active display in thebase is focused on the first focal plane of the main body of ariflescope, which allows the display generated images to maintainalignment with externally mounted accessories.

In one embodiment, the image generated from the active display in thebase is focused on the first focal plane of the main body of ariflescope, thus, the generated image is not tied to the movement of theerector tube. The generated image is independent of movement of theerector tube.

In one embodiment, light from an active micro-display is collected by agroup of optical lenses. The light from the display is reflected to abeam combiner in the riflescope main tube assembly and an image of thedisplay is formed that is coincident with the first focal plane of theriflescope. This image of the display is combined with the image comingfrom the scene (target) and is perceived as being “underneath” thetraditional wire or glass etched reticle. In one embodiment, the“traditional” reticle, which is still utilized, occludes both the imageof the scene and the image of the display. If the luminance of thedisplay is increased to sufficient brightness levels, the image of theOLED display will saturate the image of the scene and will appear toocclude the scene as well.

In yet another embodiment, the integrated display system in the base candirect generated images along a display optical axis “B,” onto viewingoptical axis A in the main body of a riflescope. The images can beredirected from the display optical axis B with a mirror or similarreflective material in the base to a beam combiner in the main body ontothe viewing optical axis A in the main body, which allows forsimultaneously superimposing or overlaying the generated images onto theimages of the scene viewed by the viewer through the optics of the mainbody. The generated images from the active display in the base aredirected toward a mirror, which reflects the images to a beam combiner.

In one embodiment, display optical axis “B” and viewing optical axis “A”are substantially parallel, although other embodiments may bedifferently oriented as desired.

In some embodiments, theGaN-based, micro-LED array may be grown on, bonded on, or otherwiseformed on a transparent sapphire substrate.

In one embodiment, the sapphire substrate is textured, etched, orotherwise patterned to increase the internal quantum efficiency andlight extraction efficiency (i.e., to extract more light from thesurface of the micro-LEDs) of the micro-LEDs. In other embodiments,silver nanoparticles may be deposited/dispersed on the patternedsapphire substrate to coat the substrate prior to bonding the micro-LEDsto further improve the light efficiency and output power of theGaN-based micro-LEDs and of the micro-LED array.

In one embodiment, the active display can be monochrome or can providefull color, and in some embodiments, can provide multi-color. In otherembodiments, other suitable designs or types of displays can beemployed. The active display can be driven by electronics.

The backlight color can be selected to be any monochrome color, or canbe white to support a full color microdisplay. Other backlight designelements can be included, such as other light sources, waveguides,diffusers, micro-optics, polarizers, birefringent components, opticalcoatings and reflectors for optimizing performance of the backlight, andwhich are compatible with the overall size requirements of the activedisplay, and the luminance, power and contrast needs.

FIGS. 16 and 17 depict representative examples of an integrated displaysystem in a base that couples to a main body, showing a display, anoptics system, and a mirror. The integrated system functions with anoptics system housed in a main body of a viewing optic, which isdepicted above the integrated display system.

Representative examples of micro displays that can be used include butare not limited to: Microoled, including MDP01 (series) DPYM, MDP02, andMDP05; Emagin such as the SVGA, micro-displays with pixel pitches are9.9×9.9 micron and 7.8×7.8 micron, and Lightning Oled Microdisplay, suchas those produced by Kopin Corporation.

The direct viewing optics can include or maintain an etchedreticle and bore sight, and retain high resolution.

In one embodiment, the utilization of an active display allows for aprogrammable electronic aiming point to be displayed at any location inthe field of view. This location could be determined by the user (as inthe case of a rifle that fires both supersonic and subsonic ammo andthus has two different trajectories and “zeros”), or could be calculatedbased upon information received from a ballistic calculator. This wouldprovide a “drop compensated” aiming point for long range shooting thatcould be updated on a shot to shot interval.

In one embodiment, the active display can be oriented to achieve maximumvertical compensation. In one embodiment, the active display ispositioned to be taller than it is wide.

In one embodiment, the active display is oriented as shown in FIG. 18 ,which allows for the maximized range of vertical adjustment 1810 of anactive reticle within a riflescope. Maximized vertical adjustment isbeneficial since it allows for the ballistic compensation of scenariosat longer range.

In one embodiment, the integrated display system further comprises aprocessor in electronic communication with the active display.

In another embodiment, the integrated display system may include memory,at least one sensor, and/or an electronic communication device inelectronic communication with the processor.

Method of Use for Range Finding

In one embodiment, the active display can display range measurementsobtained from a laser rangefinder. In one embodiment, a LRF can becoupled to a viewing optic. In one embodiment, the LRF is directlycoupled to the outer scope body of the riflescope. In anotherembodiment, a portion of a LRF is directly coupled to the outer portionof the scope body of the riflescope.

In one embodiment, the LRF is indirectly coupled to the outer scope bodyof the riflescope. In another embodiment, a portion of a LRF isindirectly coupled to the outer portion of the scope body of theriflescope.

In yet another embodiment, a LRF is not coupled to the riflescope butcommunicates with the riflescope via either hard-wiring or wirelessly.

In general operation, a LRF provides a pulse of laser light that isprojected into the scene via the projection optics. This laser lightilluminates the object, and a portion of the laser light is reflectedback toward the LRF. Part of the reflected laser light returning to thedevice is captured by the receiving optical system, and is directed to adetector. The device includes a timer starting when the laser lightpulse is transmitted and stopping when the returning laser light isdetected. A calculator portion of the device uses the elapsed time fromtransmission of the laser light pulse until detection of the returningreflected laser light to calculate the distance to the object.

In one embodiment, distance calculations are transmitted to the activedisplay, and the generated images (distance measurements orcalculations) are redirected from the display optical axis “B” onto theviewing optical axis A with a mirror and a beam combiner forsimultaneously superimposing or overlaying the images (distancemeasurements or calculations) onto the images of the scene viewed by theviewer through the viewing optics.

Windage Range Bar

In another embodiment, the active display can generate a windage range.In one embodiment, a user can supply a range of wind values, andsoftware can generate windage data, for example a windage range variancebar. In one embodiment, the windage data is transmitted to the activedisplay, and the generated images, e.g., windage range variance bar, isredirected from the display optical axis “B” onto the viewing opticalaxis “A” with a mirror and a beam combiner for simultaneouslysuperimposing or overlaying the images (windage range variance bar) ontothe images of the scene viewed by the viewer through the viewing optics.

In one embodiment, the windage data includes the minimum wind hold pointto the maximum wind hold point.

In one embodiment, the windage data is transmitted to the activedisplay, and the active display can generate a digital reticle into thefield of view at the appropriate wind hold.

Display Colors for Mental Cues

In one embodiment, the active display can generate a color display toconvey an extra level of information to the user in aquick-to-comprehend format. In one embodiment, the active display cangenerate a series of color coded symbols to indicate a readiness tofire.

In one embodiment, the active display can generate a series of colorcoded symbols to color code objects in the target scene. In oneembodiment, the active display can color code friendly forces from enemyforces. In another embodiment, the active display can color code targetsof interest.

In one embodiment, the active display can generate a series of colorcoded symbols to indicate status of windage adjustment. In oneembodiment, a red dot can indicate that windage adjustment has not beencompleted while a green symbol could indicate that windage adjustmenthas been completed.

In another embodiment, the active display can generate an aiming pointwith color. In one embodiment, the aiming point would be a red color ifproper adjustments, including but not limited to windage, range, andelevation, have not been performed. In another embodiment, the aimingpoint would be a yellow color if some but not all shooting adjustmentshave been completed. In still another embodiment, the aiming point wouldbe green if all the requisite shooting adjustments have been completed,and the aiming point is fully compensated.

In yet another embodiment, flashing and steady states of symbols may beutilized to convey similar status information regarding the adjustmentof the aiming point.

In still another embodiment, the active display can generate text thatis shown in colors to indicate status. In one embodiment, red text canindicate that in input parameter has not been entered or calculated, andgreen for text indicating a parameter which has been input orcalculated.

Markers for Impact Zone in Range Finding

In one embodiment, an active display can generate circles, squares, orother shapes to allow the user to quickly encompass or encircle theimpact zone of a projectile.

Hold-Over Estimation and Compensation

In another embodiment, the active display can generate an aiming pointcompensated for a moving target based on user input for the directionand rate of movement. For example, the user may input a rate of movementof 5 miles per hour to the left. This would be added to the windagevalue if the wind and movement are in the same direction, and subtractedfrom the windage value if the wind and movement are in oppositedirection. Then, when the aiming point and/or windage value bar areplotted on the display, the aiming point will include the proper amountof hold-over to allow the user to place the aiming point dot on thedesired impact zone and take the shot, rather than to have to place theaiming point ahead of the moving target to compensate for movement.

Team Operation via Camera and Remote Display Manipulation

In one embodiment, the active display in conjunction with a networkinterface allow for an additional level of enhanced operation and usage.In one embodiment, the reticle images of a plurality of shooters over anetwork can be viewed. Each shooter's reticle camera image is shown onone or more consoles, and network processes and interfaces enable agroup-level of coordination, training, and cooperation not beforeavailable in individual riflescopes.

Training and Coaching. In a training or coaching scenario, the coach cansee how each shooter has aligned his or her reticle on his or herrespective target. By being able to actually see the reticle alignment,the coach or trainer can then provide instructions on adjustments andrepositioning, such as by verbal instructions (e.g. by radio or inperson).

In another embodiment, the coach's console can be provided with apointing means, such as a mouse or joystick, for which control data istransferred from the console to the rifle's integrated display systemvia the network. This coach's mouse or joystick then controls anadditional dot or pointer in the display of the scope of each shooter,which allows the coach to visually show the shooter which target to use,which range marker bar to use, and where to position the reticlerelative to the target. In one embodiment, each shooter can be providedwith his or her own coach's dot so that the coach may provideindividualized instruction to each shooter.

Fire Coordination. In another embodiment, the active display can be usedin the coordination and implementation of a multi-shooter fire team. Inone embodiment, the commander of the team operates a coach's console anduses the coach's dots to assist in assigning targets to each shooter,communicating changes in reticle placement, etc.

Snapshots for Remote Review and Approval. In another embodiment, theactive display and network processes can allow the shooter, providedwith a control means, to take a “snapshot” of his or her reticle view.This snapshot of the user's reticle view can include an image of atarget of question. When the image is received by the commander orcoach, the commander or coach review the image and approve or disapprovetaking the shot. For example, in a coaching scenario, the user may takea snapshot of an animal he or she believes is a legal animal (age,species, gender, etc.) to take. If the coach agrees, the coach can soindicate by positioning or moving the coach's dot in the shooter'sreticle.

Biometric Classification of Target. In another embodiment, the snapshotof the reticle image is received by a biometric recognition and/orclassification process, such as a facial recognition system. Thebiometric recognition and/or classification process may be onboard thegun, such as being integrated into the display control logic, or may beremote to the gun interconnected via the network. The results of therecognition and/or classification process may be provided in the reticleby transmitting the results via the network to the control logic, andupdating the display appropriately.

Side-by-Side Image Display. In another embodiment, an image isdownloaded to the integrated display system via the network, and isdisplayed coincidentally in the reticle with the viewed images oftarget. A downloaded image can be used to make a side-by-side comparisonby the user of the currently viewed target with a previously-taken imageor photo of a target similar to that which the shooter is instructed ordesiring to take. For example, during doe season, a new shooter may beprovided an image of a deer doe for reference in the reticle, which canbe compared in real time to the actual animal being viewed through thescope. In a military or law enforcement application, an image of asought enemy or fugitive can be displayed in the reticle for real-timecomparison by a sniper to face of a person being viewed through thescope.

In another embodiment, the integration of the 530 nm-570 nm digitaldisplay 1910 allows for relatively higher efficacy than any other colordisplay, due to the sensitivity of the human eye. This allows for asmaller amount of power consumption, relative to powering a red or bluedisplay to the same photometric brightness.

In yet another embodiment, the integration of the 530 nm-570 nm digitaldisplay 1910 gives the end user greater ability to discern digitaloverlays from the background created by the ambient light in a daysight.

In another embodiment, the integrated display system does not require abacklight display assembly.

In yet another embodiment, the integration of the AMOLED display 2110allows for decreased power consumption, as the ability to optimize powerusage to individual pixels is now available.

In one embodiment, the integration of the AMOLED display 2110 gives acontrast ratio, which allows for a clean “heads up” style display withinthe scope. The contrast ratio allows each floating feature to beindividually targeted and represented without a low glow around thepixels.

B. Collector Lens System

In one embodiment, integrated display system has an optical system basedupon the use of optical lenses as a part of one or more lens cells,which include the lens itself and a lens cell body to which the lens ismounted. In one embodiment, the lens cell includes a precision formedbody that is generally cylindrical or disc shaped. This body has acentral aperture for mounting the lens in alignment with an optical axisof a larger optical system. The cell body can also be said to have itsown alignment axis, which will ultimately be aligned with the opticalaxis for the larger system when the lens cell is mounted therein. Inaddition, the lens cell serves as a “holder” for the lens, serves as amechanism by which the lens can be mounted to and in the larger opticalsystem, and (finally) serves as a means by which the lens can bemanipulated by and for the purposes of that system.

In one embodiment, the integrated display system comprises a collectorlens system, also referred to as a lens system. In one embodiment, thecollector lens system comprises an inner lens cell and an outer lenscell.

FIG. 23 is a representative example of a collector lens system 2310,which has an inner lens cell 2315 and an outer lens cell 2320. In oneembodiment, an outer lens cell 2320 contains at least one lens and aninner lens cell 2315 contains at least one lens. In one embodiment, theinner lens cell 2315 rotates on the inside surface of the outer lenscell 2320. As shown in FIG. 23 , an active display 1210 is coupled to aflat machined surface at the back of the inner lens cell 2315. In oneembodiment, the active display 1210 can be directly coupled to the innerlens cell 2315. In yet another embodiment, the active display 1210 canbe indirectly coupled to the inner lens cell 2315.

One advantage of the collector optics system disclosed herein is thatthe inner lens cell being combined with the micro display mount providesa solid rotational mechanical axis to position the vertical axis of themicro display.

FIG. 24 is a representative depiction of a base 220 that couples to amain body of a viewing optic, wherein the base has a collector opticssystem 2310 as part of an integrated display system. In FIG. 24 , themain body is depicted by the beam combiner 320 and the viewing opticreticle 2420.

The outer lens cell 2320 is fixed in place in relation to the viewingoptic system in the main body while the inner lens cell 2315 is allowedto rotationally float inside of the outer lens cell 2320. By placingpressure against a surface 2410 of the inner lens cell 2315 that islocated below the axis of rotation of the lens cell, the vertical axisof an active display 1210 can be aligned with the vertical axis of thereticle 1610 of the viewing optic system.

FIG. 25 is a representative depiction of one embodiment for aligning thetilt of the vertical axis of the active display with the vertical axisof the reticle. As shown in FIG. 25 , opposing set screws 2505 can betightened against a surface of the inner lens cell 2315 that is locatedbelow the axis of rotation of the lens cell. The set screws 2505 can beused to align the vertical axis of the micro display 1210 with thevertical axis of a reticle in the optical system in a main body of aviewing optic. The rotation of the inner lens cell 2315 can be retainedby tightening set screws 2505 securely against the lower surface of theinner lens cell 2315, thereby, rotationally locking the vertical axis ofthe micro display 1210 in place.

FIG. 26 is a representative depiction of a rear cut-away view of thecollector lens system 2300 with a micro display 1210 or active displaytilt adjustment mechanism. When a micro display is injected into theoptical system of a viewing optic through the use of beam combiners orwave guides, an additional method of compensation is needed in order toeliminate tilt error between the reticle's vertical axis and theinjected image of the micro display's vertical axis. Set screws 2505 canbe tightened against a surface of the inner lens cell 2315 that islocated below the axis of rotation of the lens cell, thereby aligningthe vertical axis of the micro display 1210 with the vertical axis of areticle in the optical system in a main body of a viewing optic.

FIG. 27 is a representative depiction of a method and apparatus foreliminating parallax between a micro display and the reticle in anoptical system in the main body of a viewing optic. An outer lens cell2320 contains at least one lens on the right hand side of FIG. 27 and aninner lens cell 2315 contains at least one lens on the left hand side ofFIG. 27 . The inner lens cell 2315 slides along the optical axis on theinside surface of the outer lens cell 2320. A micro display 1210 iscoupled to the inner lens cell 2315. A spring 2710 is installed betweenthe outer lens cell 2320 and the inner lens cell 2315 to cause the cellsto separate when not under a compression force.

FIG. 28A is a representative depiction of a base, which has thecollector optics system 2300, coupled to a main body of a viewing optic.In FIG. 28A, the main body is depicted by the beam combiner 320 and theviewing optical reticle 2810.

The outer lens cell 2320 is fixed in place in relation to the viewingoptic and the inner lens cell 2315 is allowed to float inside of theouter lens cell 2320. By forcing the inner lens cell 2315 forward by useof a screw or a wedge 2820 that places force on the back of the innerlens cell/active display mount, the axial position of the image ischanged so that the focal plane of the micro display image lies on thesame plane as the viewing optic reticle in the main body of the viewingoptic. Thus, parallax between the micro display and the reticle iseliminated.

The position of the inner lens cell is kept in place through the actionof the spring pressing outwards against the screw or wedge. Parallaxbetween the active display and the reticle can be eliminated withoutchanging the amount of light that is collected from the active displayand without degrading the image quality of the system.

By implementing the use of the spring between the inner and outer lenscell and the force on the back of the inner lens cell/micro display, themaximum amount of light can be collected from the micro display andprovides a rapid, simple, and accurate method of adjustment.

In one embodiment, the inner lens cell 2315 and the outer lens cell 2320can comprise two or more lenses. In yet another embodiment, the lenssystem can comprise 3, 4, 5, 6, 7, 8, 9, 10 or greater than 10 lenses.Lens can be obtained from a variety of commercial manufacturersincluding but not limited to LaCroix Optics (www.lacroixoptics.com) andDiverse Optics (www.diverseoptics.com).

In one embodiment, the collector lens system comprises a five lenssystem comprising 2840, 2850, 2860, and 2870, with 2840 being closest tothe active display, and 2870 being farthest from the active display. Inone embodiment, the inner lens cell 2315 comprises 2840 and 2850. In oneembodiment, the outer lens cell 2320 comprises 2860 and 2870.

In one embodiment, the spacing between lens 2 in the inner cell and lens3 in the outer cell is changed when the inner lens cell moves axiallyalong the inner diameter of the outer lens cell. This causes the focalplane of the image of the display to shift and is used to null outparallax between the projected display image and the passive reticle inthe main body of the viewing optic.

In one embodiment, the focusing of the display image onto the firstfocal plane of the optic system in the main body is accomplished bychanging the air spacing between lens 2 and lens 3, of a 5-lens system,which is accomplished by varying the position of the inner lens cellwith respect to the outer lens cell.

In one embodiment, lens assemblies may also be assembled together withina lens barrel, which is an integral mechanical structure holding aseries of lenses. It is used to position the lenses axially and radiallywith respect to each other, and to provide a means of interfacing thelens assembly with the system of which it is a part. Lens elements areradially positioned by the inside diameter or ID of the barrel wall. Theoutside diameter or OD of the lens elements are ground to fit ID of thebarrel wall. The axial position of the lens elements is accomplished bycutting lens seats during assembly. The lens elements can then beconstrained on the seats by epoxy, retaining rings, etc.

C. Reflective Material

In one embodiment, the integrated display system comprises a reflectivematerial 1230. In one embodiment, the reflective material 1230 is amirror. In one embodiment, the integrated display system comprises oneor more mirrors. In one embodiment, the integrated display systemcomprises two, three, four or more mirrors.

In one embodiment, the mirror is positioned at an angle from 30° to 60°,or from 30° to 55°, 30° to 50°, or from 30° to 45°, or from 30° to 40°,or from 30° to 35° relative to the emitted light of the display.

In one embodiment, the mirror is positioned at an angle from 30° to 60°,or from 35° to 60°, 40° to 60°, or from 45° to 60°, or from 50° to 60°,or from 55° to 60° relative to the emitted light of the display.

In one embodiment, the mirror is positioned at an angle of at least 40°.In one embodiment, the mirror is positioned at an angle of 45° relativeto the emitted light of the display.

In one embodiment, and as shown in FIG. 29 , the tilt of a mirror 2910along the vertical axis is able to be adjusted by use of a screw orsimilar mechanism. By turning a screw in against the base or rear of themirror 2910, the angle at which the image of the micro display isreflected into the beam combiner can be changed. This correspondinglychanges the tilt of the focal plane at the viewing optic's reticle 2930of the optical system in the main body of a viewing optic. Using thisadjustment, parallax error can be eliminated between the micro displayand the reticle along the vertical axis.

In one embodiment, the mirror is fastened to the base with one or morescrews. In one embodiment, the mirror is fastened to the base using achemical compound such as an epoxy, a resin, or a glue or combinationsthereof.

In one embodiment, the position of the mirror can be adjusted inrelation to the beam combiner to eliminate any errors, including but notlimited to parallax error.

In one embodiment, the position of the mirror can be adjusted inrelation to the active display to eliminate any errors, including butnot limited to parallax error.

2. Power System

In one embodiment, the base that couples to the main body of the viewingoptic has a power system. In another embodiment, the base of a viewingoptic has a cavity. A battery cavity can be integrated into the basethat couples to the main body of a viewing optic.

FIG. 30 is a representative schematic of a base 220 with a batterycompartment 3005, wherein the base 220 is coupled to the main body 210of a riflescope 3000. As shown in FIGS. 30 and 31 , the battery cavity3005 extends from each side of the base to encase a battery, includingbut not limited to a CR123 battery. The CR123 battery has increasedpower capacity and discharge as compared to smaller batteries or coinstyle batteries.

In one embodiment, the battery cavity 3005 is integral to the base 220so that only the battery cap is needed to protect the battery from theenvironment. No additional sealing is required.

In one embodiment, the battery cavity 3005 in the base 220 is locatedcloser to the objective assembly 3010 of the main body 210 of a viewingoptic as compared to the ocular assembly.

FIG. 32 is a representative depiction of the battery compartment 3005integrated into the base 220. In one embodiment, the cavity 3005 isdesigned to have the positive side of the battery inserted first with amechanical stop at the bottom of the battery cavity to prevent improperinstallation and operation of the battery.

In one embodiment, the integrated battery cavity 3005 can use the samegasket as the base 220 uses to the main body 210 of the riflescope. Thisprovides a more reliable seal and eliminates a mechanical device as aseparate battery cavity is not required. Secondly, there is nomechanical device securing the battery cavity since it is integratedinto the base. This reduces the need for any mechanical interface forsecuring the battery compartment. Because there is no need formechanical locking of the battery cavity, the integrated batterycompartment reduces the points of failure for a traditional batterycompartment.

The integrated battery compartment eliminates any obstacles that are inthe way of the user. The integrated battery compartment is located underthe viewing optic out of the way of any of the adjustments and knobsfound on traditional viewing optics. The integrated battery cavity is asignificant advancement as it allows the necessary space to accommodatea larger battery.

In one embodiment, the viewing optic can be set-up in a manner tominimize battery drain and to maximize battery life. For example, theviewing optic with a laser rangefinder is activated when an operatorpresses a button or switch. A range finder designator is displayed onthe screen. An external range finder's output laser will coincide withthe designator through an initial calibration step when zeroing theviewing optic. When the external rangefinder is activated by theoperator, information is sent to the viewing optic wirelessly or via thecommunication port signaling the device that information has beenreceived and needs to be displayed.

If the viewing optic is turned on and no data is received from anexternal device, the viewing optic will power down after a user settime. After displaying received information from an external device, thepower down timer is started and will power down the device if no furtherbutton presses are registered.

If more information is received from an external device, the screen willbe cleared of the prior information and the updated information will bedisplayed and the power down timer will be started. This cycle cancontinue as many times as the operator chooses.

During the time when information is displayed on the screen, a cantindicator is displayed on the screen. This is refreshed from anaccelerometer communicating with the microcontroller on a time interval.When the microcontroller is in sleep mode, the integral buttons on theviewing optic will control the brightness of LEDS illuminating a glassetched reticle. When the viewing optic is operating, control of theseLEDS becomes suspended and the brightness of the screen will be alteredduring the corresponding buttons presses.

3. Picatinny Mount

In one embodiment, the disclosure relates to a viewing optic having amain body and a base with a battery compartment and a picatinny mountthat can couple to the battery compartment. In one embodiment, aremovable picatinny mount is attached to a protruded battery compartmentthat is incorporated into a base coupled to a main body of a riflescope.

FIGS. 33-35 are representative schematics of a riflescope with a mainbody 210 and a base 220 coupled to the main body 210, with the basehaving a battery compartment 3005 that can attach to a picatinny mount3305. In one embodiment, the picatinny mount 3305 is aligned with thebattery compartment 3005 and secured with fasteners.

By attaching the mount 3305 to the battery compartment 3005 of the base220, it utilizes the material needed to make the cavity 3005 for thebattery. This eliminates the need for any additional material from thebase, thereby making the viewing optic lighter and less invasive.

In one embodiment, the mount is located towards the objective of theturrets and parallax knob so as to not intrude on the user's ability toadjust the riflescope. Further, the top ring is removable allowing foreasy attachment of an accessory device, such as a laser rangefinder. Byutilizing the picatinny mount disclosed herein, no additional structuralsupport from the top portion of the ring is needed since the integratedbase secures the riflescope.

In one embodiment, the mount incorporates a cantilevered picatinny railthat extends forward towards the objective of the riflescope. Thisallows a weapons mounted laser range finder to sit directly over thebell of the riflescope. This style of mount allows for decreased shiftof impact and increased accuracy of the ranging device. It decreases thepotential for shift of impact since there are fewer variables that mayaffect the ranging device from acquiring the desired target.

4. Data Ports

In one embodiment, the disclosure relates to a viewing optic with a mainbody and a base with an active micro display for generating an image andcombining the generated image into the image of the scene in the FirstFocal Plane of the main body of the viewing optic, wherein the base hasaxially orientated data ports for interfacing with ancillary devicesincluding but not limited to remote control switches and laserrange-finders.

FIG. 36 is a representative schematic of a riflescope 3600 with a mainbody 210 and a base 220 with axially oriented data ports 3605. In oneembodiment, the viewing optic can have one axially oriented data port.In another embodiment, the viewing optic can have two or more axiallyoriented data ports.

By utilizing an axially oriented data port 3605, the top down profile ofthe overall viewing optic is minimized, thereby increasing therobustness of the mounted system and its connections.

5. External Video Sources

In one embodiment, the active display in the base can be used as theoptical train or optical system of a clip on device, including but notlimited to a thermal imaging system and a night vision system.

Thermal imaging systems allow for various waves of the electromagneticspectrum to be imaged and relayed to the user, which typically cannot becaptured by the human eye. Traditional thermal weapon sights arecomposed of two systems paired together: an infrared optical system,which views the scene and a visible wavelength optical system consistingof a micro display and lenses to recreate the image in front of theriflescope. There are also instances of catalytic photon enhancement,creating what us known as “night vision” systems. However, clip-ondevices are typically attached to the rifle rail in front of the mainbody of the riflescope. This setup blocks all of the ambient lighttypically imaged by the scope, and allows for use of the digital imageonly. In order to switch back to the traditional image, the user mustremove the system from the rail. This can cause an impact shift due tothe alignment setup that you go through each time the sight is changed.These clip-on units also tend to be large, due to the need for aneyepiece/imaging system behind the digital display in the units. Intraditional systems, any live video feed would be a completely digitalimage, including the visible spectrum output.

FIG. 37 is a representative schematic of a riflescope 3700 with a mainbody 210 and a base 220 with an active display 1210 and collector optics1220 that can be used as the optical system of a thermal imaging unit3705. The active display 1210 generates an image that is focused on afirst focal plane of the main body of the scope, using a beam combinerto integrate the image into the traditional day optic. The integrationof the digital display allows for the user to overlay the digital imageonto the ambient day optic. With the digital display disclosed herein,the clip-on unit does not have to be removed from the front of theviewing optic to view the ambient day optic. Rather, the digital displaycan be turned on and off as needed.

The integration of the digital display allows for zero image shift whenswitching between day visible and digital optic. Since the system isfully integrated, there is no need to zero each time the digital opticis turned on. The system is synchronous, due to the alignment of thecombiner optical system.

In one embodiment, the integration of the digital display makes up theoptical train that would typically be the rear half of a clip-on unit.Because there is already a micro display in the base of the viewingoptic, the thermal sight would only need the infrared optics; the imagecreated by the thermal sensor can be transmitted to the active display,which is already incorporated into the base of the viewing optic. Byintegrating a thermal or NV sight in this manner, the thermal/NV devicewill be much shorter and lighter than current weapon sights on themarket. This allows for the design of smaller lighter systems, sincehalf of the optical train is now integrated directly into the base thatcouples to the main body of a viewing optic. There is no need for a rearoptical system or display to be integrated into the clip-on unit thatcontains the sensing device.

Additionally, if the thermal weapon sight were to be mounted off to theside of the riflescope so that the thermal optics did not occlude theriflescope objective, then it would be possible to overlay a thermalimage overtop of the visible image that the user would be viewing. Thiswould have the benefit of being able to highlight humans, animals, oranything with a heat signature that stands out in an otherwise neutraldaylight scene.

In one embodiment, the integration of the digital display disclosedherein creates the advantage of having live video feed into the focalplan of a viewing optic, without interruption of the day visible sight.

In one embodiment, the integration of the digital display allows forseamless integration of imaging overlays, such as live thermal imagingview, and hyperspectral overlay systems. The visible image is nowanalog, rather than another digital display.

In one embodiment, the integration of the digital display disclosedherein creates the advantage of continued image feed, even if power wereto suddenly drain on the digital system. A true analog image would stillbe available, which would not be the case in traditional digital outputsystems.

In one embodiment, the integration of the digital display allows formultiple types of imaging systems to be mounted separate from the frontof the viewing optic. A thermal imaging system can be aligned to thebottom or side of the viewing optic and still feed that image directlyonto a focal plane within the main body of the viewing optic.

6. EMI Permeable Window

In one embodiment, the main body, the base or both the main body and thebase of a viewing optic can have a window that is sealed with a materialtransparent to the electromagnetic waves used for the wirelesscommunication. Transparent materials include but are not limited toplastics, resins or epoxies.

In one embodiment, the window allows EM waves to propagate from thecommunicating device with reduced interaction from the metallic body ofthe viewing optic. This increases the rate at which data can betransmitted. It also allows the wireless communication device to operateat a lower power level due to reduced signal losses.

III. Additional Sensors/Devices

In another embodiment, the disclosure relates to a viewing optic with amain body and a base with an integrated display system and one or moresensors. In one embodiment, the sensors include but are not limited to aGlobal Positioning System, accelerometers, a magnetometer, MEMS ratesensors, tilt sensors, laser rangefinder.

A. Pointing Angle, Target Location, and Communication

In one embodiment, the viewing optic can have inertial MEMS Rate Sensorsto determine the pointing angle of the weapon in inertial space. Exampleproducts are the LCG-50 by Systron Donner and the SiRRS01 by SiliconSensing. In another embodiment, accelerometers can be incorporated intothe embedded electronics to determine absolute tilt angle of the viewingoptic and track weapon accelerations due to general movement or a firingevent.

To support targeting, in various embodiments, the viewing optic can havea GPS and/or digital compass. In one embodiment, the GPS and/or digitalcompass can be integrated into the viewing optic, for example, as boardlevel modules. In another embodiment, the GPS and/or digital compass canbe associated with a separate device that communicates with the viewingoptic.

Several manufacturers offer custom of the shelf modules for GPS anddigital compass functionality that are small form factor and have lowpower consumption characteristics. These devices are designed to beintegrated into embedded components. For example, Ocean ServerTechnology makes a OS4000-T compass with 0.5 deg. accuracy and has apower consumption under 30 ma and is less than ¾″ square. An example ofa GPS device is the DeLorme GPS2058-10 Module that is 16 mm×16 mm and isavailable in a surface mount package offering 2 meter accuracy.

In one embodiment, the viewing optic can have a data interface thatprovides one or both of wired and wireless capabilities designed tointerface to systems such as the BAE Personal Network Node and theemerging SRW radio. These interfaces provide various communicationscapabilities, such as range, sensor, and other tactical data (e.g.anti-fratricide detector, environmental sensors, etc.). This uniquefunctionality is used in various embodiments to obtain and communicateenvironmental, target, and situational awareness information to thecommunity of interest. Generally speaking, the various embodiments aredesigned to enable the war fighter to quickly acquire, reacquire,process, and otherwise integrate data from a variety of passive andactive sources into a ballistic firing solution thereby increasing theshooter's effectiveness.

In another embodiment, the sensors provide information to the activedisplay in order to generate real time position data of differenttargets onto the first focal plane of the main body of the viewingoptic. In another embodiment, the sensors are part of an external devicethat communicates with the integrated display system.

By using these sensors in the viewing optic, or on an external devicethat is rigidly connected to the viewing optic, or on a weapon that theviewing optic is mounted to, the exact position of the viewing optic canbe obtained, as well as the exact direction that the viewing optic ispointed, and external targets can be calculated in relation to theviewing optic position and aimed direction.

As the user moves the viewing optic around or as targets move inrelation to the viewing optic, the position of the targets would beupdated continuously and in real time by the sensors communicating withthe integrated display system, so that by viewing through the viewingoptic the user would be able to see where the targets are in relation towhere they are looking.

This approach has strong utility in military applications where you mayhave personnel in different locations that are trying to communicate aspecific target location to one another. For example, with Close AirSupport (CAS), a pilot may be flying an aircraft and a unit on theground may be relying on the aircraft to drop a bomb on a target. Oftentimes, it is difficult for the unit on the ground to relay to theaircraft the exact location of the target. The process of relaying thetarget information between the ground unit and the aircraft is oftenreferred to as “talking on to the target,” and involves communicatingwhat the unit or aircraft is seeing in their field of view, such as whatlandmarks might be visible near the target and so on.

This process often takes quite a bit of time and can cause confusionbecause things often look different from the air than they do on theground. It is critical that each unit be sure that they are all lookingat the same target, because if the aircraft mistakes the target they maydrop a bomb on friendly units, or non-combatants.

By allowing location and position sensors to communicate with the activereticle display of the integrated display system, these issues aresolved. The user of the viewing optic can designate a target in theirscope, the scope knows the GPS location of the scope, the exactdirection it is pointing and distance to the target and can calculatethe exact GPS coordinate of the target. This information can be fed intoa universal system, such as Link 16, that all friendly units areconnected to. Now the aircraft can simply look at a display in theiraircraft and the new target is displayed on their map as soon as anotherunit designates it.

This makes finding targets much quicker and the confirmation that bothunits are looking at the same target much easier. Accuracy is extremelyimportant in determining target locations, thus, the active displaygenerated images need to be displayed in the first focal plane of themain body of the viewing optic. If the generated image from the activedisplay were put into the second focal plane of the viewing optic, thenthe target locations would only be accurate when the viewing opticreticle was at its “zeroed” location. If the user of the viewing optichad dialed anything on their turrets, for example to engage a long rangetarget, then all of the target information in the display would beshifted the amount dialed in the turrets and not be accurate.

By using this with the active display images injected into the firstfocal plane, the displayed data is agnostic of any adjustments made tothe reticle position and is automatically compensated for. This meansthat target data in the field of view is always accurate.

B. Environmental Sensors

In one embodiment, the viewing optic can have one or more pressure,humidity, and/or temperature sensors designed to collect and useenvironmental data for ballistic correction purposes. The sensors areavailable in miniature configurations suitable for integration into theviewing optic. An example of a miniature, low power, water proof,barometric pressure sensor is the MS5540 from Intersema. This componentmeasures 6.2×6.4 mm.

In one embodiment, the sensors can be coupled to the main tube of theviewing optic or to the base of the viewing optic.

C. Uphill and Downhill

In one embodiment, the viewing optic can have a z-axis accelerometerthat can be used to measure tilt angle of the scope with respect tovertical. This tilt angle can be integrated into a ballistic solution atthe time of target selection. Once the target is selected, the systemmay be able to automatically integrate actual uphill or down tilt intothe ballistic solution and display the solution into the first focalplane of the viewing optic so that the digital reticle or correctedaiming point is displayed correctly. This can provide for a very fastand effective means of aiming in long range uphill or downhillengagements.

IV. Viewing Optic with Display System and Laser Range Finder

In one embodiment, the disclosure relates to a viewing optic having amain body and a base with an integrated display system, and a laserrangefinder. In one embodiment, the laser rangefinder is coupled to theviewing optic. In another embodiment, the laser rangefinder isindependent from the viewing optic and communicates with the viewingoptic, either wirelessly or through a cable.

In one embodiment, the laser rangefinder couples to the viewing opticvia a mounting rail that attaches to the base through the batterycompartment.

In one embodiment, a laser rangefinder can be used to determine distanceto target. In various embodiments, the laser transmits in the near IRfor covertness. A typical wavelength used for laser rangefinder devicesoperating in the near infrared (NIR) is 905 nm.

In one embodiment, the specific laser power and spectral characteristicsare selected to meet range and eye safety requirements of the viewingoptic. The rangefinder is of sufficient power to produce accuratemeasurements out to, illustratively, 1500 meters, 2500 meters orwhatever effective range is associated with the firearm or weaponintended to be used with the viewing optic. For rangefinder operation,in some embodiments a single button control is dedicated for making orexecuting a rangefinder measurement.

In one embodiment, the range to target may be communicated to the activedisplay that generates an image of the range to target and superimposesthe range to target onto the first focal plane of a viewing optic whenviewing the target scene.

In one embodiment, the viewing optic has a computing device withballistics calculator capabilities. In one embodiment the main body ofthe viewing optic has a computing device with ballistics calculatorcapabilities.

In one embodiment, a laser rangefinder can be used to measure a targetdistance, calculate projectile ballistics and communicate the correctedaim point to an active display in an integrated display system, whichthen superimposes the image of the corrected aim point onto the firstfocal plane of a viewing optic with a reticle attached to a moveableerector lens system.

Importantly, because the active display generated image is combined withthe image from the target in front of the first focal plane and thenfocused onto the first focal plane, the target image and display imagenever move in relation to one another. Therefore, any aiming referencecreated by the digital display will always be accurate, regardless ofhow the moveable erector system is adjusted.

When an external laser range finder feeds range information to theriflescope, an aiming reference or laser designator will need to becreated by the digital display in order for the user to know where inthe field of view the LRF is aiming in order to accurately hit thecorrect target with the laser. The digital display image and the targetimage of the objective lens system in the main body of the riflescope donot move in relation to one another. Therefore, the digital laserdesignator will accurately show the user the correct location of the LRFlaser point of aim, no matter how the turrets have been adjusted to movethe moveable erector lens system.

On the other hand, if the digital display image was integrated into theoptic system anywhere behind the first focal plane then when the turretsare adjusted, and the erector lens system is moved/tilted, then theimage of the digital display would move in relation to the target imageand the digital LRF designator would move in relation to the actuallaser point of aim. This could lead to an incorrect range measurement ifthe user dials any elevation or windage adjustment into the turrets andforgets to dial back to the original position the turrets were set towhen the user aligned the digital reticle with the actual laser point ofaim.

In addition, when a traditional riflescope is zeroed to the rifle, theuser will typically select a “zero” range, often times 100 yards, thatis used align the riflescope reticle with the point of impact of therifle projectile. This is usually accomplished by adjusting the turretsof the riflescope, and thus the angle of tilt of the erector lenssystem, in order to align the reticle with the point of impact of theprojectile. After the initial “zero” of the riflescope has been set, theturrets allow the user to further make adjustments to the riflescopereticle position in order to compensate for targets at different rangesor for changing wind drift variables that affect where the point ofimpact of the projectile may change from the initial “zero” position.

If the digital display were to be integrated into the riflescope systembehind the first focal plane then the ballistically calculatedcorrection factor to the point of aim would have the potential to beincorrect if the user had made any adjustments to the turrets from theinitial “zero.” For example, if a ballistic calculator determined thatthe correction required 10 milliradians of elevation adjustment to hitthe target, the digital display would place an aim point 10 milliradiansbelow the center of the crosshair. However, if the user had dialed 5milliradians into the elevation turret from the initial “zero” position,the digital aim point would actually be aiming 15 milliradians below theinitial “zero.”

By injecting the digital display into the first focal plane of the opticsystem of the main body of a riflescope, it allows the digital displayto be totally unaffected by any change in the turret adjustment orposition of the erector system. This means that in the example above,the digital aim point would actually appear only 5 milliradians belowthe center of the reticle, for a total of, the correct, 10 milliradianballistic drop (user had previously dialed 5 milliradians into theelevation turret from the initial “zero” position). In short, injectingthe digital display image into the first focal plane of the optic systemof the main body renders the digital display image completely agnosticto any change in the turret position and thus the erector lens systemmovement/tilt, which provides the needed accuracy.

In one embodiment, the laser range finder capability providesdynamically defined ballistic solutions based upon data acquired. Therange to target may be used by the on-board computer when processingtracer trajectory to determine the best point along the measuredtrajectory path to use for determining the ballistic correction for thenext shot.

In one embodiment, the laser rangefinder is integrated into the scopeand has a dedicated outgoing laser transmission port. In one embodiment,the optical path of this dedicated laser axis is positioned in thecorner of the housing so it is unobstructed by the main objective lens.The detection path for the incoming reflected laser signal is throughthe main objective of the scope where the light is directed to a photodetector by a near IR beamsplitter. This arrangement takes advantage ofthe relatively large aperture of the main objective lens to increase thesignal to noise of the measurement.

FIGS. 38 through 44 provides photographs of a viewing optic 3800 havinga main body 3810 with an optical system and a base 3820 coupled to themain body 3810 having an integrated display system, with a laser rangefinder 3830 coupled to the top of the main body 3810. The viewing optic3800 can have two auxiliary ports 3805 for communication with anexternal source. The viewing optic 3800 can have a picatinny mount 3305that couples to the outside of a battery cap for a battery cavity 3005in the base 3820.

FIGS. 45 through 46 provide depictions of a viewing optic 4500 having amain body 4510 with an optical system and a base 4520 coupled to themain body 4510 having an integrated display system, with a laser rangefinder 4530 coupled to the top of the main body 4510. The viewing optic4500 can have a single auxiliary port 4535 for communication with thelaser range finder 4530.

FIGS. 47 and 48 provide depictions of a viewing optic 4700 having a mainbody 4710 with an optical system and a base 4720 coupled to the mainbody 4710 having an integrated display system. In certain embodiments,the viewing optic 4700 can have a picatinny mount 4730. In certainembodiments, the viewing optic can have an auxiliary port 4735.

V. Additional Embodiments

1. Digital Zeroing

In one embodiment, the disclosure relates to method for using a digitalreticle for alignment and zeroing purposes. In one embodiment, theviewing optic has a physical reticle and a digital reticle, with thephysical reticle being connected to the erector system. The user “zeros”the physical reticle by using turrets to move the reticle and erectorsystem so that the center of the reticle coincides with the bullet pointof impact.

After the physical reticle is zeroed, the digital reticle must also bezeroed. Since the digital reticle is formed by an active or digitaldisplay that is fixed in position, the only way to zero or align thedigital reticle is by using a digital means. The digital reticleposition can be moved by the user so that the center of the digitalreticle coincides with the center of the physical reticle.

In another embodiment, digital zeroing can also be used with a laserdesignator. When used in conjunction with an external laser rangefinder, the viewing optic laser designator must be aligned with thedirection that the laser range finder is pointing. Most external laserrangefinders have a visible laser and an infrared laser. The infraredlaser is the laser that actually measures the range. The visible lasercan be turned on an off and coincides with the aim of the infraredlaser. The visible laser allows the user to see where the laser isaiming. Once the visible laser is turned on, the user can then digitallyadjust the laser designator to coincide with the point of aim of thevisible laser. Then the visible laser can be turned off and the user canuse the laser designator in the viewing optic display to ensure accurateaiming of the laser rangefinder.

2. Holographic Waveguide

In one embodiment, the disclosure relates to a viewing optic having amain body with a first optical system and a base with active display anda holographic waveguide. In one embodiment, the integration of theholographic waveguide reduces the package size and weight of atraditional beam combining system. The integration of the holographicwaveguide can increase the overall transmitted brightness ratio, suchthat a greater percentage of each optic system light gets to the enduser.

FIG. 49 is a representative depiction of a viewing optic 4900 with anoptical system in a main body 4910 and a base 49 having an activedisplay 1210 and a holographic waveguide system 4925. The holographicwaveguide system 4925 spans the main body 4910 as well as the base 4920.A digital or active display 1210 generates an image to the collimationoptic 4930, which sends the image to the in-coming hologram waveguide4926. The image exits the waveguide via the output hologram 4927 and theimage is injected into the first focal plane 4930 of the optical system4940.

In one embodiment, the integration of the holographic waveguide reducesthe need in specialized coatings made for beam combiners. In addition,the integration of the holographic waveguide disrupts the need for amirror system, alleviating the need for complex mechanical alignmentsystems.

The integration of the holographic waveguide allows you to create a copyof the complex optical system needed to image a display, eliminating theneed for a complex system to be put into every system.

The integration of the holographic waveguide allows for the use of LCOS,LCD and OLED systems to display information within an optical system.The nature of the system allows for various types of illuminationsystems in conjunction with the different types of displays used withinthe system.

The use of a holographic waveguide allows for the implementation ofnon-static illuminated reticles. The reticles can be changed just asimages on a screen are changed. The holographic waveguide allows fordaylight bright reticle systems without the need for traditionalillumination methods.

3. Tracking Bullet Trajectory

One of the difficulties associated with long range engagements is theability to determine the accuracy of an initial shot so that a timelycorrection can be made to improve the accuracy of the next shot. Atraditional technique used to determine the round's point of impact isto attempt to detect bullet trace and/or actual splash point of bullet.This can be difficult in many long range engagements. In the case of asniper team, the follow up shots also require feedback from the spotterto get the pertinent data back to the shooter. This can take severalseconds using only verbal communications.

In one embodiment, the viewing optic can have an imaging sensor adaptedto detect image frames associated with a bullet flight path andcommunicate said image frames to a computing device, which can thencalculate bullet trajectory therefrom.

In one embodiment, the viewing optic with a main body and a base with anintegrated display system can allow tracer rounds to be detected byon-board image processing capabilities so as to determine the bullet'strajectory just before it impacts the target area. In one embodiment,this data can be communicated back into a ballistics computer therebyquickly and efficiently creating a follow up firing solution for thesecond round, which can be communicated to the active display and thecorrected aiming point superimposed into the first focal plane of themain body of the viewing optic.

Automating the feedback loop with trajectory and splash point detectionby computer and combining this to the active display and superimposingan electronic aiming point correction in the first focal planeadvantageously decreases the total time required to make an accuratesecond shot. This time reduction can be at a critical point in theengagement process. After the first shot is made, the window ofopportunity to make a second shot can quickly narrow, especially ifdelays extend past the point in time when the sonic boom of the initialshot reaches the intended target.

Environmental conditions and windage drifts can have substantial impacton the ballistic trajectory of the round over large distances. Forinstance a M193 bullet can drift about 4 feet in a modest 10 mphcrosswind at 500 yards, Windage effects become even more exaggerated atgreater distances since the speed of the bullet decreases as the rangeand total time of flight increases.

A variety of tracer round options are available. A standard tracer isused conventionally by the shooter to see the trajectory of the bulletsin-flight path. A tracer round can emit light in the visible or IRspectrum depending on the composition of the tracer material. The latteris effective when the shooter is using night vision equipment. Inaddition some tracers can emit light dimly at first and then brighten asthe round travels downrange. A fuse element can control when the tracerlights up after firing of the round in order to delay igniting thetracer material until the bullet is well downrange. The fuse delaymitigates the risk of the tracer revealing the shooter's firinglocation.

In one embodiment, a viewing optic with an integrated display system canuse tracer rounds to detect, determine and/or display a bullet'strajectory just before it impacts the target area. In one embodiment,covert tracers that have long delay fuses and emit in the near IR region(700 nm to 1000 nm) of the electromagnetic spectrum can be used. Lightemitted in the near IR region is invisible to the human eye, but can bedetected by an imaging sensor using conventional glass optics. A tracerround of this type can be particularly effective in maintaining theshooter's covertness for Sniper operations while providing a significantautomated bullet tracking capability for accurately determining nextshot correction requirements. Thus, various embodiments are adapted tocooperate with one or more types of tracer rounds to implement thefunctions described herein.

Since the imaging sensor in the daylight embodiment is also sensitive tovisible light, a standard daylight tracer can also be used for bullettracking. In both the visible and near IR cases, the tracer rounds cantake advantage of having long delay fuses to increase covertness as thesystem only needs to detect the bullet's flight in the final momentsbefore impact.

In one embodiment, a camera associated with a viewing optic can recordthe trajectory of the bullet and using the suite of sensors embeddedinto the viewing optic, it can calculate the exact geo-positionaltrajectory of the bullet, as well as the bullet's point of impact.

In another embodiment, the viewing optic may also use a stabilizedcamera to compensate for recoil from the firearm. The viewing opticwould accurately track the movement of the stabilized camera, andcompensate for that movement to accurately calculate the geo-positionaltrajectory of the bullet. This embodiment would allow the shooter totrack their own trajectory and compensate for any misses moreaccurately.

In both embodiments, the geo-positional trajectory of the bullet couldthen be shared to other users who also active displays in devices theyare using, such as another riflescope, spotting scope, or goggles usinga microdisplay or holographic technology to display the trajectory intotheir field of view.

In one embodiment, the tracking of the bullet's trajectory incorporatescapturing video frame images of the glowing tracer bullet in flight. Thespatial location of the bullet in selected image frames is extractedthrough image processing techniques and then correlated with data fromother video frames to establish the bullet's trajectory.

Image frames are selected for processing based on correlation with thefiring event. When the round is fired from the weapon, the time ofmuzzle exit is immediately determined by processing accelerometer dataobtained from an on-board weapon axis accelerometer included in variousembodiments. A correlation window from the time of muzzle exit is thenstarted where various embodiments begin frame by frame processing ofvideo images to identify therein a small cluster of pixels associatedwith the tracer round at a particular X-Y position in space. The frameimages may be taken with an exposure time that is optimized to capturethe bullet as it transmits a small number of individual pixels in theX-Y frame. Since the frame rate of the camera and time of muzzle exit isknown, the bullet's distance from the weapon in each frame can beestablished using the known flight characteristic of the bullet. Thisdata is contained in the onboard tables pertinent to each weapon and itsassociated rounds or, alternatively, received from a tactical networkcommunication with the weapon sight.

If an absolute range to target is known from a laser rangefindermeasurement, the position of the round at the target range can becalculated by determining the point in the trajectory that correspondsto the target range. The elegance of this technique is that themeasurement is done from in-flight data and does not rely on bulletimpact with a physical surface. The position calculated would correspondto an angular elevation and azimuth relative to the weapon's positionand can be used to determine the ballistic pointing correction neededfor increased accuracy. As part of this next shot ballistic correctioncalculation, various embodiments use inertial pointing angle data tocalculate the relative reference point between inertial pointing angleof the gun at muzzle exit and the pointing angle at the time of splash.This allows the calculation to take into account any angular movement ofthe gun that occurred during the bullet's time of flight to targetrange.

V. Viewing Optic with Advanced Reticle Features

A. Active Display Pattern based on Magnification Setting

In one embodiment, the disclosure relates to a viewing optic having amain body and a base with an integrated display system, wherein theactive display of the integrated display system generates multiplereticle patterns that are projected into the first focal plane of thefield of view.

In one embodiment, the disclosure relates to a viewing optic having amain body and a base with an integrated display system, wherein anactive display of the integrated display system generates a reticlepattern based on magnification level.

In one embodiment, the disclosure relates to a viewing optic having amain body with one or more sensors that can track or monitor themagnification level of the optic and a base with an integrated displaysystem, wherein an active display of the integrated display systemgenerates a reticle pattern based on magnification level. Depending onthe magnification level, the active display system can generatedifferent reticle patterns that are optimized for different opticalmagnification levels. In one embodiment, the active display of theintegrated display system can automatically switch between reticlepatterns based on the magnificent level.

In one embodiment, the viewing optic with an integrated display systemcan project digital features or aim points that are optimized for thespecific magnification setting being used.

In one embodiment, the main body of the viewing optic has a sensorassociated with a magnification adjustment mechanism of the sightingdevice to produce a signal indicative of an adjustment of the opticalmagnification of the viewing optic. The viewing optic further includesan electronic controller in communication with the sensor and the activedisplay of the integrated display system. The electronic controller inresponse to the signal produced by the sensor, communicates to theactive display to generate a reticle pattern, which is vie viablethrough an eyepiece in a field of view thereof superimposed upon animage of a distant object.

In some embodiments, the electronic controller and active display areconfigured to produce a first reticle pattern, such as a close-quartersreticle pattern, in response to the signal indicating a firstmagnification setting; and, in response to the signal indicating asecond magnification setting greater than the first magnificationsetting, the electronic controller and active display may produce asecond reticle pattern that is distinct from the first reticle pattern.For example, the second reticle pattern may be a long-range reticlepattern, such as a sniper reticle.

In some embodiments, the sensor may include an electro-mechanical oroptical digital encoder (which may be rotational or linear), apotentiometer, a combination of one or more magnets and one or more halleffect sensors, or other suitable device operable for sensing theposition or movement of the magnification adjustment mechanism andproducing a corresponding electrical signal. In one embodiment, thesensor and described in FIGS. 69 and 70 .

In one embodiment, the active display is not in the main body of theviewing optic.

In one embodiment, one or more reticle patterns can be selected fromincluding but not limited to 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14,15, 16, 17, 18, 19, 20, and greater than 20. In one embodiment, theviewing optic with an integrated display system can chose between atleast 10, or at least 20, or at least 30, or at least 40 or at least 50reticle patterns.

In one embodiment, the active display of the integrated display systemprojects reticle patterns into the first focal plane of the field ofview that are based on specific magnification settings. Upon a change inmagnification setting, the reticle pattern generated from the activedisplay switches so that the aim point is immediately useful for theoperator. The switching of the reticle can be based on the magnificationsetting.

As way of example, and not to be limited, at a 1× magnification setting,the active display can generate a small center dot that is projectedinto the first focal plane. Upon a magnification change to 8×, theactive display generates a cross hair pattern with long range hold overdots that are projected into the first focal plane. The sensordetermines a change in magnification, which is communicated to acontroller, which changes the reticle pattern of the active display.

In one embodiment, the viewing optic with an integrated display systemprojects information and aim points that are designed to aid theoperator in engaging targets at short and long ranges. In oneembodiment, multiple “pages” of information or reticle patterns can bedesigned and loaded into the system and different pages can be displayeddepending upon the magnification setting.

In one embodiment, the reticle pattern from the active display isprojected onto an etched reticle of the first focal plane. Projectingthe digital reticle onto an etched or fixed reticle provides necessaryprotection in the event of a system failure.

FIG. 53 is a representative depiction of a Close Quarter Battle reticle5300 at 1× magnification. The thick arched lines 5305, the primaryhorizontal line 5307, the primary vertical line 5309, numbers and arrowsare components of an etched reticle. The center dot 5310 is generatedfrom an active display of an integrated display system. This type ofreticle is used for close quarter battle; the center dot represents afast target acquisition aim point.

FIG. 54 is a schematic representation of the reticle from FIG. 53 butwith the magnification setting of the viewing optic at 8×. As can beseen, the center dot 5310 being projected from the active display hasbecome obtrusively large under 8× magnification.

FIG. 55 is a representative depiction of a reticle pattern 5500 thatprovides useful information when the viewing optic is set at amagnification setting of 8×. The thick arched lines 5502, the primaryhorizontal line 5504, the primary vertical line 5506, numbers and arrowsrepresent the etched reticle. The center aim point 5510, the 6ballistically compensated windage dots 5520, and the square in the upperleft 5530, which represents a rangefinder designator displaying ahypothetical range to target are components generated by the activedisplay.

FIG. 56 is a representative depiction of the reticle pattern 5500 at alow magnification setting.

With references to FIGS. 53-56 , when the optical magnification settingis at 1X, the reticle pattern 5300 includes etched reticle features5305, 5307, and 5309 as well as a first set of multiple marks 5310 (suchas a circle and/or an aiming dot) generated from the active display andprojected onto the first focal plane reticle. Preferably, the reticlepattern 5300 formed at least in part by the first set of marks 5310, isa type of close-quarters reticle (CQB reticle) having minimal marks toprovide a less cluttered viewable area, such as illustrated in FIG. 53 .

When the optical magnification setting is increased, an electroniccontroller and the active display (in response to a signal received froma sensor, including but not limited to the sensor described in FIGS. 69and 70 ) replace/alter/change the first reticle pattern with a secondset of multiple marks, which form (at least in part) a second reticlepattern 5500 that is distinct from the first reticle pattern 5300 andwhich typically includes at least some different functionality.

For instance, the second reticle pattern may include different aimingfeatures and additional marks, such as relating to estimating distance,calculating windage and elevation adjustments, or other suitable markscommonly used in ranging reticles such as shown in FIG. 55 .

It can be seen therefore, that creating multiple “pages” of features andreticle patterns for the active display, storing them in a memorysystem, and automatically switching between the reticle patter s as theoperator changes magnification settings on the viewing optic will beextremely useful.

B. Active BDC Reticle

Ballistic Drop Compensating (BDC) reticles are designed to have hashmarks located on the portion of the vertical cross hair that is locatedbelow the horizontal cross hair. These hash marks are designed atspecific distances to try and closely match a specific or set ofspecific ballistic profiles.

However, the current BDC reticle designs are fixed designs. This isbecause the reticles are made using wire, metal, or etched on glass.Once the reticle is made and installed in the riflescope it can't bechanged without taking the reticle out and installing a new one, whichcan only be practically accomplished by sending the scope back to themanufacturer.

In one embodiment, the disclosure relates to a viewing optic having amain body with an optical system and a base having an integrated displaysystem with an active display that can generate a BDC reticle that canbe changed manually by the user at any time, or even automatically bythe software and sensors of the viewing optic in real time.

To generate the BDC reticle for the viewing optic disclosed herein, theriflescope can be programmed for the specific ballistic profile of therifle and the to be fired cartridge. Second, the viewing optic hassensors, as described above, such as temperature, pressure, humidity,cant angle, inclination angle, that can aid in giving real time updatesto the BDC reticle so that it is as accurate as possible for allconditions. This allows the BDC reticle to be custom tailored to eachrifle and the specific shooting conditions.

The BDC reticle generated in real-time by the active display allows theshooter to have an accurate system for shooting at various distancesaccurately and quickly.

As shown in FIG. 57 , the reticle 5700 has standard etch and fillportions including a primary horizontal line 5702, a primary verticalline 5704, and numerical markings and hash marks along the primary andvertical crosshairs. Reticle 5700 also has patterns and marks generatedby the active display and projected onto the first focal plane reticle.The active display marks in the form of a BDC reticle include thenumerical markings 5710 (100-900 on the vertical axis in quadrants 3 and4). As this portion is projected from the digital display, it can beupdated in real time.

In addition to an active BDC reticle, there are times where auser/shooter might find themselves in a position where they areproviding cover for other individuals in an area where targets maypresent themselves quickly and at varying ranges. An example might be asniper who is on top of a building looking down an alley or a road thathas cross streets or doorways. The active display can be used inconjunction with a variety of sensors embedded into the riflescope, suchas compass, cant angle, inclination angle, GPS, etc. to be able toaccurately determine the direction the riflescope is pointed.

Using a viewing optic having environmental sensors, an integrateddisplay system having an active display for generating and projecting aBDC reticle into the first focal plane, and a rangefinder, a user willbe able to range known landmarks, such as doors, windows, cars, etc. anduse the controller and active display to place a range marker on thoselandmarks. These range markers are projected into the first focal planeand visible through the viewing optic. The environmental sensors allowthe user to move the viewing optic around to view other targets, but therange markers would remain on the targets.

FIG. 58 is a representative image of a BDC reticle generated by theactive display and projected onto a first focal plane reticle, withrange to potential targets indicated. A viewing optic having a main bodywith environmental sensors and a base having an integrated displaysystem with an active display for generating a BDC reticle will allowthe user to mark multiple targets in one or more areas with distanceindications on the target markers. Then, if a target were to presentitself near a target marker, the user would be able to quickly identifythe range to the target without having to range the target. The user canthen employ the active BDC reticle to quickly hold in the correctlocation to engage the target.

C. Reticle Compensated for Firearm Cant

In a traditional riflescope, when shooting long range, it is importantthat the firearm and scope are level when taking a shot. When a bullettravels over a long distance, the bullet is affected by gravity to adegree that the shooter must take into account. Gravity pulls the bullettowards the ground in a consistent direction creating “bullet drop.”Shooters compensate for this bullet drop by aiming higher than theirtarget so that by the time the bullet reaches the target, it has droppedto the appropriate height, such that it hits the target.

FIG. 59 is a representative depiction of cant angle. It can be clearlyseen that the triangle is a right triangle with the 10° angle at the topand the right angle at the bottom. The 10 milliradian leg has become theside of the triangle that is the hypotenuse and represents a cantedvertical section of crosshair. However, gravity is acting on thevertical leg of the triangle.

Using trigonometry, the length of the vertical leg can be solved withthe following equation: Cos 10°=x/10 milliradians. Solving for x resultsin a value of 9.85 milliradians. So, in this example, while theuser/shooter may have held or dialed 10 milliradians, they onlycompensated for a 9.85 milliradian shot. At long range, this is easilyenough to miss the target.

In one embodiment, the disclosure relates to a viewing optic with anintegrated display system that uses an active display to generate areticle that can compensates for cant of the firearm. The user canseamlessly shoot at distance without having to worry about cant angle.

In a traditional riflescope the reticle is a physical cross hair that iseither metal, wire, or a pattern that is permanently etched on glass.This means that the cant of the reticle is always fixed. However, withthe active display technology for generating a real-time reticle, byoverlaying a digital reticle onto the passive image, the digital reticlecan be changed at any time. In one embodiment, the viewing optic has aninternal cant sensor that can instantly orient the reticle generated bythe active display to compensate for cant angle.

FIG. 60 is a representative depiction of a reticle 6000 with marks andpatterns oriented for cant and generated by an active display of anintegrated display system. The primary horizontal line 6002 and theprimary vertical line 6004 are provided by the passive or etched orfixed reticle. The aiming point generated by the active reticle 6020compensates for cant and is projected or overlaid onto the passivereticle. The pivot point 6010 is at the center of the reticle. In thiscase, an electronic controller/micro-controller would use theinformation gathered from cant angle and inclination angle sensors andapply software logic and communicate with the active display to adjustthe generated image aiming point 6020 to reflect the new zero position,associated geometry and hold points that correspond to the orientationof the firearm at that point in time. The user would shoot off thedigital reticle generated by the active display, instead of the passiveor fixed reticle.

In another embodiment, the active display of the integrated displaysystem can generate a digital reticle that compensates for cant, as wellas for shooting at an inclined or decline angle, by adjusting the aimpoint up or down on the digital reticle. This would eliminate the needfor a cosine indicator, which is often used to compensate for shootingin these types of situations.

D. Digital Reticle with Wind Drift Indicators

In a traditional riflescope, reticles that have wind indicators areusually a glass etched reticle. Often these reticles will have a gridpattern or rows of dots to allow the user to have a reference point touse to aim with and compensate for wind speed. The problem with thesereticles is that they are fixed in shape and size, since they arephysically and permanently etched onto a piece of glass.

In one embodiment, the disclosure relates to a viewing optic having amain body and a base with an integrated display system having an activedisplay for generating a digital reticle that uses wind drift indicatorsthat compensate for the range to target. In one embodiment, the digitalreticle is overlaid onto a passive reticle. By using a digital reticlethat is overlaid on a passive reticle, the viewing optic can have areticle that can adapt real-time wind holds to the ballistics, range,and environment of the specific situation.

Typically, the longer the range, the more effect a crosswind has on abullet. By using a digital reticle, the wind holds can be spread outmore as the distance increases to compensate for wind values at thespecific range for the target.

FIG. 61 is a representative depiction of a reticle 6100. Multiplecomponents or markers are provided by the passive reticle including theprimary horizontal crosshair 6102 and the primary vertical crosshair6104. The active display of the integrated display system generated andprojects a target that was ranged at 500 yards 6105 and wind holds 6110for the specific conditions. The end of the secondary horizontal line(across the main vertical line) would equal a 5 mph wind drift, the nextdot would be 10 mph, and the outer most dot would be 15 mph. The imagesgenerated from the active display 6105 and 6110 are overlaid onto thepassive reticle.

FIG. 62 is a representative depiction of a reticle 6200. Multiplecomponents or markers are provided by the passive reticle including theprimary horizontal crosshair 6202 and the primary vertical crosshair6204. The active display of the integrated display system generated andprojects a target that was ranged at 1000 yards 6210 and wind holds 6220for the specific conditions. The end of the horizontal line (across themain vertical line) would equal a 5 mph wind drift, the next dot wouldbe 10 mph, and the outer most dot would be 15 mph. The images generatedfrom the active display 6210 and 6220 are overlaid onto the passivereticle. It can be seen that the secondary horizontal line 6220 extendswider, and the wind dots are spread further to the sides compared to the500 yard (FIG. 61 ) solution to compensate for additional wind driftinduced when the bullet travels a longer distance.

E. Reticle with Center Grid for Second Shot Correction

In the past, passive reticles have been designed to allow the shooter tohave many reference points for shooting in varying conditions andvarying ballistics. However, since the variety of conditions andballistics vary so widely, these reticles have tended to have manyfeatures on them, such as grids of lines or dots, that cause the reticleto appear cluttered, or busy to the user.

In one embodiment, the disclosure relates to a reticle system comprisinga digital reticle generated with an active display overlaid a passivereticle. The use of the digital reticle allows information to be shownas needed and as appropriate, which eliminates the need for certaininformation to be displayed on the passive reticle, thereby providing acleaner or more easily discerned passive reticle.

In one embodiment, the disclosure relates to a viewing optic having apassive or analog reticle that is designed to work most efficiently inconjunction with an active reticle. The active reticle technology allowsthe viewing optic to do the complicated calculations and display aballistic solution for the user. Typically, the ballistic solution willnot be in the center of the field of view or the center of the passivereticle cross hair. This gives the user the option to either hold overcenter on the ballistic solution, or to dial the turrets until theballistic solution is in the center of the field of view and in thecenter of the passive cross hair to take the shot.

In one embodiment, the disclosure relates to a viewing optic with ananalog and digital reticle that will allow the shooter to mosteffectively and efficiently make a second shot correction, whileminimally obstructing their field of view like previous passive reticleshave done, which use extensive grids of lines and dots.

FIG. 63 is a representative depiction of a wide angle view of a reticle6300 at low magnification. A less obtrusive row of dots is used belowthe horizontal cross hair. This passive reticle can be used as a backup,in the event the active display cannot be generated because the batterypower or electronics of the viewing optic fail.

FIG. 64 is a representative depiction of a close-up view of the centerportion of the reticle 6400. FIG. 64 provides a view at highermagnification. This image shows a small grid 6410 generated by theactive display of the integrated display system, which is located at thecenter of the reticle. This will allow the user to make accuratemeasurements of first shot impact location to make accurate second shotcorrections.

In one embodiment, the grid 6410 generated by the active display iswider than it is tall. This is specifically designed since calculatingelevation of an impact is more accurate than estimating wind drift of afirst shot. In this embodiment, the small plus features of the smallgrid are not illuminated but are very fine features, which allow veryprecise measurement.

The active or digital reticle should get the first shot very close,therefore, the center grid can be much smaller than a typical passivereticle, which requires an extensive grid that covers a significantportion of the field of view below the horizontal cross hair.

VI. Auto Brightness Adjustment

As discussed throughout the application, the integrated display systemallows digital images generated by an active display to be overlaid ontop an image of an outward scene. This active display is injected intothe image of the outward scene using illuminated portions of thedisplay. For the display to be most usable it is desirable to have ahigh contrast ratio between the brightness of the passive scene and theilluminated display such that both can be easily seen. If the display istoo dim the user will not be able to see it. If the display is toobright the display will overpower the passive scene.

In one embodiment, the disclosure relates to viewing optic having a mainbody with an integrated display system and a light sensor that candetect the specific target brightness and compensate for it.

FIG. 71 provides a representative schematic of a viewing optic 7000 witha main body 7005 and a base coupled to the main body 7010. The main body7005 has an optical system for viewing an image of an outward scene anda beam combiner 7020 with a photo sensor 7025 and a light filter 7030located above the beam combiner 7020. This allows the photo sensor tolook directly at the target scene, without creating an obstruction inthe field of view. The base 7010 has an integrated display system 7015having an active display for generating an image that is projected intothe first focal plane of the viewing optic.

The photo sensor 7025 and light filter 7030 generate a high contrastratio between the brightness of the image of the outward scene and thegenerated image from the active display.

In one embodiment, the transmission band of the filter in front of thephoto sensor can be tuned to be narrow enough so that only thebrightness of the target will be measured and the additional light fromthe display system will not be measured, which would distort themeasurement.

VII. Viewing Optic with Auto-Ranging Capabilities

In one embodiment, the disclosure relates to a viewing optic with anintegrated display system that incorporates the use of a camera to aidin an auto-ranging. In one embodiment, the disclosure relates to asystem comprising a viewing optic with an integrated display system, acamera to aid in an auto-ranging, and a laser range finder.

In one embodiment, the disclosure relates to a viewing optic having anintegrated display system and a camera that incorporates imagerecognition technology. The systems and methods disclosed herein greatlyincrease the speed of acquiring a target solution, and eliminate theneed of a button press that may affect point of aim. In addition, thesystems and methods disclosed herein integrate artificial intelligenceinto the system to determine the quality of the ranged target solution.

In one embodiment, the viewing optic has a camera that incorporatesimage recognition technology. In one embodiment, the camera can beattached to either the viewing optic having an integrated display systemor a firearm and would point towards the point of aim of the riflescope.

In one embodiment, the camera has artificial intelligence to detect atarget and communicate with an active display of the integrated displaysystem to highlight the target. In another embodiment, the artificialintelligence system can be incorporated into the viewing optic. In oneembodiment, the artificial intelligence system can be located in thebase coupled to the main body of the viewing optic.

In another embodiment, a thermal imaging camera lacking imagerecognition technology can be used. This would allow the thermal imageto be communicated to the active display and overlaid onto the image ofan outward scene in the viewing optic. The viewing optic could beprogrammed to only display “hot spots” of interest. For example, hotspots that indicate human heat, or vehicle heat, etc. Eliminatingartificial intelligence will greatly reduce the power consumed by thesystem. In addition, all appropriate hot spots would appear in the fieldof view of the viewing optic, allowing the user to evaluate each one todetermine if the target was valid or not.

After identifying a valid target, the user would simply move the viewingoptic so that the LRF designator in the FOV was over top of the desiredhot spot. Once the LRF designator was aligned with the hot spot, thesystem would automatically trigger the LRF to take a range at that hotspot. After taking a range, the viewing optic could either display ahold point for the range of the target or could simply show the rangeand the user could use the Active BDC mode and hold on the active BDCreticle for the appropriate measured range to the target.

An additional capability to the system is that it could automaticallydetect if the hot spot remained within the LRF designator long enough toget a valid range. If not, it would wait to display a range until thehot spot remained within the LRF designator the appropriate length oftime to achieve a valid target acquisition before displaying a solution.This would eliminate the second problem with pressing a button.

In one embodiment, the disclosure relates to the technology and methodof using an overlaid camera image projected into the first focal planeof a viewing optic, and using that image in conjunction with a LRFdesignator to automatically range a target.

VIII. Viewing Optic with a Photosensor to Conserve Power

In one embodiment, the disclosure relates to a viewing optic with anintegrated display system and a power saving system. In one embodiment,the power saving system is located in a base coupled to the main body ofthe viewing optic. In one embodiment, the power saving system comprisesa proximity sensor. In one embodiment, the proximity sensor is incommunication with a microcontroller.

In one embodiment, the power saving system can be used to place theviewing optic in a sleep or standby mode when a user/operator is notlooking through the optic. In one embodiment, the systems and mechanismscan wake or activate the viewing optic when a user/operator is detectedbehind the eyepiece of the optic.

Current methods of putting the electronics to sleep or into standby areby using a “time out” feature, which is disadvantageous if the optic isbeing used for Close Quarter Battle work since the optic must stay onfor an indeterminate amount of time as long as there is an operatorlooking through it. An accelerometer can also be used to detect motionand thus turn the system on. The disadvantage of that method is that ifan operator is doing observation then the gun may have very littlemovement for long periods of time and thus go to sleep, even though theoperator is still looking through the optic.

In one embodiment, the disclosure relates to a system to conservebattery power by turning on the viewing optic when there is an operatordetected behind an eyepiece of the optic.

In one embodiment, the power saving system can be used in anyelectro-optics compatible with implementing a proximity sensor that iswithin a few inches of where the operator's face will be when using theoptic.

In one embodiment, the disclosure relates to a viewing optic having amain body and a base coupled to the main body, wherein the base has awindow in the back of the base toward eyepiece.

In one embodiment, the base has a proximity sensor installed into acarrier and the carrier is installed into the window located at the endof the base toward the eyepiece. The proximity sensor can communicate asignal to a microcontroller in the base or main body when the proximitysensor detects a reflection that is within a few inches of the window.The distance at which an object will activate the sensor can be adjustedeither at the factory or a software option can be built into the userinterface to allow the operator to either adjust the sensitivity of thesensor or disable/enable the auto sleep/standby feature.

FIG. 72 is a representative depiction of a viewing optic 7200 having abase 7205. The base 7205 has a window 7210 located toward the eyepieceof the main body of the viewing optic. A proximity sensor and carrier7215 are located in the window 7210, which is located below theeyepiece.

FIGS. 73 and 74 are representative depictions of a viewing optic 7200having a base with with a power saving system, with the viewing opticmounted on a rifle. It can be seen that an operators face will be withina few inches of the back of the optic. The sensor 7215 in the base 7205of the viewing optic 7200 will detect a reflection from the operator'sface, thus waking the optic up from a sleep mode. When the operatorremoves his/her head from the view position, the sensor will no longersee a reflection and will put the viewing optic into a sleep or standbymode.

IX. Viewing Optic with Power Rail

In one embodiment, the disclosure relates to a viewing optic having amain body and a base with an integrated display system, wherein theviewing optic can be powered by an external power source that is housedin the host firearm. In one embodiment, the viewing optic has a mainbody and a base coupled to the main body, wherein electrical pins arebuilt into the base to provide power from the firearm to the viewingoptic. In another embodiment, the viewing optic can be powered by thefirearm using electrical pins that are built into the remote keypadassembly.

In one embodiment, the discloser relates to methods and systems toprovide additional power for extended periods of time to the viewingoptic.

In one embodiment, the disclosure relates to a viewing optic with a mainbody and a base coupled to the main body, wherein the base has PCBs thatare being used to control a display, sensors, and user interface of theviewing optic. In one embodiment, the base has power input pins thatprotrude through the base and contact a power pad. In one embodiment,the power pad is built into a Picatinny rail.

In one embodiment, the PCBs are located in a position that allowsinteraction with the input pins. In one embodiment, the pins are sealedagainst the base of the riflescope to keep the interior of theriflescope protected from the environment.

FIGS. 75 and 76 are representative depictions of a viewing optic 7500having a main body and a base 7510 with power pins 7520 protrudingthrough the base 7510 of the viewing optic 7500.

FIG. 77 is a representative side profile of viewing optic 7500 showingthe power pins 7520 protruding through the base 7510 of the viewingoptic 7500.

FIG. 78 is a representative view of the side profile of viewing optic7500 with the base of the viewing optic made transparent to show thepower pins 7520 which that are attached to the built in PCBs 7530.

In another embodiment, power supplied by the picatinny rail on thefirearm could be delivered to the viewing optic through a remote keypad,which is used to control the viewing optic. In this scenario, the powerpins are connected to the PCB that is in the remote keypad and theyprotrude through the built in recoil lug in the remote keypad housing.Power is then sent through two dedicated lines in the cable into thebase of the riflescope.

FIG. 79 is a representative image of the top of the remote keypad 7900.

X. Viewing Optic with a Single Keypad with Multiple Functions

In one embodiment, the disclosure relates to a system comprising aviewing optic having an integrated display system and a remote keypadsystem with more than one function per keypad button. In one embodiment,the remote keypad can control more than one aspect of functionality ofthe viewing optic, i.e. more than one function per button. In oneembodiment, the function of the button depends on the state of either acontrol signal or software bit.

In one embodiment, the disclosure relates to a remote keypad thatexpands the control that a user/operator has over a viewing optic and/orauxiliary devices that are used with the viewing optic.

In one embodiment, the disclosure relates to a keypad for a viewingoptic and/or one or more auxiliary devices that are used with theviewing optic. In one embodiment, more than one function is assigned toa single button of the keypad, wherein the desired function can bedetermined with a software bit or a separate mechanical switch. This cansignificantly increase the functionality of the viewing optic.

In one representative embodiment, in a first mode, a button can changethe brightness of the display and in a second mode, the same button canactivate an infrared pointer on the system. Using the same button formore than one function keeps the remote keypad small and simple with theminimal number of buttons required.

FIG. 83 is a representative depiction of a keypad with three buttons. Aremote keypad associated with a viewing optic has 3 buttons. The topbutton 8305 is used to increase the brightness of the display, themiddle button 8310 is used to fire the laser rangefinder to range atarget and the bottom button 8315 is used to decrease the brightness ofthe display. The functionality of each button depends on the mode ofoperation.

In one embodiment, the keypad can have 2, 3, 4, 5, 6, 7, 8, 9, 10, ormore than 10 modes of operation. In one embodiment, the keypad can be incommunication with a processor setting from 10 to 50 modes of operationfor the keypad. By way of example, a keypad in communication with aprocessor having 10 modes of operation for the keypad, would provide 10functions for each button, with the functionality determined by the modeof operation.

Several methods can be used to change the functionality of the buttons.In one embodiment, when a user/operator presses and holds a button onthe remote for a period of time, the micro controller changes thefunction of one or more buttons. In one embodiment, an operator canpress and hold one of the 3 buttons for a prolonged period of time, forexample, 1 second, and this will signal the micro controller inside ofthe viewing optic to change a bit that assigns new functions to thebuttons. In one embodiment, pressing and holding the top button 8305 fora period of time can set mode A, pressing and holding the middle button8310 for a period of time can set mode B, and pressing and holding thebottom button 8315 for a period of time can set mode C. Varying the timeeach button is engaged can activate further modes of operation. Forexample, holding button 8305 for five seconds can active mode A,engaging button 8305 five quick taps can active mode F.

In another embodiment, the functionality of the remote keypad buttonscan be changed is through a separate mechanical switch on the viewingoptic. In one embodiment, a mechanical switch can have 3 distinctpositions, which are in communication with 3 separate bits or programsin the micro controller. These bits or programs can be used to assignvarious functions to the remote keypad buttons.

A representative example is shown in FIG. 84 . The viewing optic has aswitch 8400 in communication with a remote keypad 8300. A first setting8405 can assign the top button 8305 of a remote keypad 8300 the functionto increase display brightness, the middle button 8310 could fire thelaser rangefinder, and the bottom button 8315 could decrease displaybrightness. When the mechanical switch 8400 is set to a second setting8410, the function of the top 8305 and bottom buttons 8315 can beprogrammed to turn on and off auxillary pointing lasers on the viewingoptic and the middle button 8310 can still be programmed to fire thelaser rangefinder. When the mechanical switch 8400 is set to a thirdsetting 8415, the functions of the 3 buttons could be altered again. Forinstance, if the viewing optic is equipped with a digital magneticcompass and location and landmark data was saved to the memory of amicro controller then information about the position of objects could bedisplayed inside of the field of view of the viewing optic (augmentedreality data).

In one embodiment, the keypad is in communication with a processor ofthe viewing optic that allows varying modes of operation to be assignedto each button or switch of the keypad. For example, in one mode ofoperation, the buttons of the keypad have specific functions for markinga target of interest. The operator can use the laser rangefinder torange a target and, use the heading data from a digital magnetic compassto “mark” a target of interest inside the field of view. The buttons onthe keypad could be assigned functions that are specifically suited forthis task.

The center button on the keypad could be used to fire the laserrangefinder to range the target. Once the target is ranged, the top andbottom buttons could be used to select from a predefined list ofdescriptors to label the target, e.g. “landmark,” “friendly,” “hostile,”“unknown” etc. Once the operator is done with this action, themechanical switch can be changed to quickly assign functions back to theremote keypad buttons that allow the operator to change brightnesssettings, activate an infrared laser, or obtain a ballistic solution fora target downrange.

XII. Viewing Optic with a Relative Coordinate Mapping System

In one embodiment, the disclosure relates to technology and a method ofusing a viewing optic with an integrated display system to accuratelytag and track targets using a relative coordinate mapping system, and/ordrone technology.

Soldiers need to be able to accurately identify the location of enemytargets and to share that location with other soldiers, close airsupport, etc., and to be able to see those targets easily by having themoverlaid into the field of view of their primary optic. The most obviousway to achieve this is using a combination of GPS, compass heading,altitude, inclination, and range finding sensors. However, there aredisadvantages in relying on GPS, such as GPS signals require direct lineof sight to the GPS satellite, which may not always be possible. Usingrelative coordinate technology and/or the use of drones, the need forGPS can be diminished. Relative Coordinate Technology becomes feasiblewhen used in conjunction with a viewing optic having an integrateddisplay system.

In one embodiment, a user would be able to point the viewing optic withan integrated display system at a landmark or target and “tag” it. Ifthe user “tagged” several targets, then a relative location map could becreated from the tagged targets. These tagged targets could betransmitted to a viewing optic of other users, who would see thosetagged targets displayed in the field of view. All this target datawould then be stored locally in one or memory devices in the viewingoptic.

In one embodiment, the user could also use drones either as analternative to tagging targets, or as a supplement to tagging targets.This would work by launching a “cloud” of many small or micro dronesthat would contain cameras and the appropriate sensors to fly over abattlefield and begin tagging and marking landmarks. The drones couldshare that information with each other and back to the users who wouldhave it displayed in the active display of their viewing optic.

By using relative coordinate technology and/or a cloud of drones, thedisadvantages of GPS can be overcome:

-   -   With multiple users and multiple viewing optics, there becomes        an inherent redundancy in the stored target data. When using a        cloud of drones, that redundancy can be increased even further.        With redundancy, it becomes much less likely that a signal or        data would be lost.    -   GPS requires sending and receiving data over very long distances        to and from satellites in orbit. By using other users who are in        the same battle space, or a cloud of drones in the same battle        space, the network is much closer to the users and target, which        increases the accuracy of the user and target coordinates.    -   GPS is much easier to block, since there are a limited number of        GPS satellites. With a cloud of users and/or drones, it becomes        much harder to block all the signals and creates more        redundancy.    -   Eliminating the need for a GPS module makes the viewing optic        less bulky.
